# Change Log

## [0.99.27] - 2026-08-10

"Scratchpad Recording"

### Added

-   Edit / Preferences / Metronome
    -   Added check-boxes to activate the Metro, Record, and Thru ports.
    -   Added a button to set the metronome to the internal hard-wired
        settings, which uses the drum channel.
-   Pattern editor.
    -   Added an "owning sequence number" member to eventlist.
        Could be useful in pasting notes across patterns.
    -   Added a dialog to more easily add RPN or NRPN control events
        to a pattern. They can also be save as a MIDI macro in the
        'ctrl' file.
    -   Ctrl-T in the piano roll brings up the Tools menu.
-   Added functions for splitting and joining 14-bit MIDI values.
-   Added more default MIDI macros. See the bottom of the file
    data/linux/qseq66.ctrl.

### Changed

-   Background recording. This feature has been fixed and upgraded to
    do "scratchpad recording". This is like background recording,
    but requires the user to enable it. It immediately adds a new
    pattern in record mode, enables expansion of the pattern, and
    starts play. Improvise at will until done, stop recording,
    and use the new pattern (or delete it) as desired.
-   Port-mapping.
    -   The Recreate button clears the port map and recreates it,
        including any devices plugged in while Seq66 runs.
-   Pattern editor.
    -   Macros now inserted at progress location, not at the "L"
        marker.
-   Main Session tab, MIDI macros.
    -   Macros now require clicking the Send button. This makes the
        operation success/failure clear.

### Fixed

-   Main window.
    -   Show inactive/unavailable ports as disabled in the global buss
        dropdown list.
-   Pattern editor.
    -   The "left align" pattern fix was broken by the new automatic
        insertion of an initial time-signature event. Now we bypass
        all initial meta events to get the amount of time-shift needed.
    -   Fixed "right align" in a similar way.
    -   Fixed pasting across patterns to show a box where the notes
        will go.
-   Live grid.
    -   When Edit / Preferences is closed, the metronome and scratchpad
        statuses (enabled/disabled) are reflected in the buttons.
-   MIDI macros.
    -   Fixed minor bugs sending macros via MIDI-control-out.

### Removed

-   Nothing removed.

## [0.99.26] - 2026-07-15

"MIDI Learn"

This version introduces the Seq66 flavor of MIDI Learn. Learning
the grid controls for the pattern-grid and mute-groups is nearly
automatic, while learning the automation controls is a bit different
from other MIDI applications. Uses a "Learn Manager" dialog.

### Added

-   MIDI learn! See that section in the user manual for details.
-   The new "font-fix.qss" style sheet can be used to correct
    font sizes (and only font sizes).
-   More tool-tips.
-   Control actions via keys and buttons have been added
    to augment MIDI Learn.
    -   automation::slot::mod\_set\_0
    -   automation::slot::record
-   Pattern editor.
    -   Added "Jitter" to the pattern editor tools.
-   Event editor.
    -   Added a button to enlarge the pattern by one measure.
    -   Replaced the "Ticks" check-box with a "BBT" button
        to cycle through display of time in B:B:T, H:M:S, or
        ticks.
-   Command-line.
    -   Added a --new option to avoid loading the most-recent
        file for the current run.

### Changed

-   Most of the 'qss' files have been tweaked.
-   Updated the creation of menus and actions to specify font size.
    However, currently not used, in favor of styles.
-   The --investigate option turns off the log file for easier
    debugging.
-   Changed the shortcut (accelerator key) for Import / Project
    Configuration from Ctrl-J ("LF") to Ctrl-G ("BEL") so that
    Ctrl-J can be used to activate automation::slot::thru.

### Fixed

-   A missing NSIS application ("makensis") no longer causes a build
    error.
-   In Edit / Preferences / MIDI Input for control, the output buss
    being enabled was checked instead of the input buss, causing no
    input port to be enabled.
-   Event editor.
    -   Fixes to some event handling, such as pitch-wheel.
    -   Added filling in of some data depending on the event selected.
-   Command-line.
    -   Fixed --help and --version abbreviations so that the application
        stops after, say, options --hel, for example.

### Removed

-   Slots.
    -   automation::slot::mod\_LR\_loop
-   Event editor. Removed the "Ticks" check-box. Use the BBT button
    instead.

## [0.99.25] - 2026-06-06

"Mesonry Opens Doors!"

A major refactoring of Seq66 to use Meson and qmake, while ditching
the overly-cumbersome autoconf build. Replaced bootstrap with
work.sh to match other "66" projects. Makefiles and configure.ac,
etc. are gone.

Required moving the seq\_qt5 moc/ui-related files to the
seq\_qt5/src/gui. In addition, some connect() calls were updated to
work with either Qt5 or Qt6. The Meson build also works in Windows,
and, since Qt is statically linked, qseq66.exe is self-contained.

### Added

-   The lib66 library project is downloaded automatically as a
    Meson subproject. It contains a few useful types and macros
    incorporated into new code.
-   Worked on documentation and scripts to build the Windows version
    on Linux. However, it has proven difficult to get all the Qt
    code and tools to work with Mingw.
    -   meson.mingw.cross
    -   contrib/scripts/mingw-qt-build.sh
    -   contrib/notes/mingw-qt-build.text
-   Event editor. Added checks on timestamps plus a button to
    increase the pattern size by one measure.
-   Build info. Added file and string processing to use with the
    file /etc/os-release (if present on the computer) to show
    the "pretty name" of the build distro.
-   Added these options to work.sh:
    -   --no-jack
    -   --no-jack-transport
    -   --no-nsm
    -   --no-cli
    -   --no-gui

### Changed

-   Moved user-interface modules (i.e. "cpp", "hpp", and "ui" files)
    such as qsmainwnd and qseditoptions to seq\_qt5/src/gui.
-   The button in Help / About is now an OK button, and the
    version name display now shows the minor version number.
-   Changes for Qt6:
    -   "No such signal QButtonGroup::buttonClicked(int)" in
        qclocklayout.cpp and qseditoptions.cpp updated to
        use a lambda connect() if Qt6 is in use.
    -   Still more qt6 deprecations found and fixed.
-   JACK Session support is now disabled by default, since it is
    deprecated. Can enabled via './work.sh --jack-session' or via
    'meson setup ...'.
-   About dialog. If the 'usr' dark-theme setting is enabled,
    the HTML links are a more visible color than the blue default.
-   Updated the documentation to show the input buss number in
    a grid slot.

### Fixed

-   The libraries used in the build are helper libraries, internal
    to the project, and hence pkgconfig files are not made,
    and the libraries a not installable.

### Removed

-   The autotools install was installing the Seq66 headers and
    libraries. The library files (a and so) were huge, it turns out.
    Much larger than the qseq66 executable built with static
    libraries. We don't need the headers, and the static build
    yields a much smaller install footprint for qseq66. The headers
    and libraries are no longer installed,

## [0.99.24] - 2026-05-01

Mitigates issue #144, where note and drum-note painting was
not being snapped in a sensible way.

### Added

-   Pattern editor.
    -   Added the display of a drum-note's name when in drum
        mode and hovering near a drum-note to modify it.
    -   Improved the drums module/class for this addition.
    -   Added the ability to show hex numbers for the standard
        MIDI controller events.
    -   Added two small buttons:
        -   One toggles showing certain data pane numbers in
            hexadecimal versus decimal format.
        -   The other toggles showing the 5 horizontal line
            level numbers, useful when the display is cluttered
            near the beginning.
-   Event editor.
    -   Added the ability to show hex numbers for the standard
        MIDI controller events.

### Changed

-   Backed autoconf version from 2.72 to 2.71 re issue #145.
-   Edited all forms in QtCreator to use Qt 6 namespaces.
-   Fixed some more QMouseEvent x()/y() deprecations found by Clang
-   qseq66.rc.
    -   Change auto-rc-save to default to false.
    -   Added another flag so that the 'rc' file can be saved at
        first run (no existing configuration files) without saving
        auto-rc-save=true.
    -   Auto save enabled either by user setting in Edit /
        Preferences / Session or by a relevant change in
        configuration at run-time.

### Fixed

-   Main window.
    -   When the "Remap & Restart" pops up, if a pattern
        editor is open, the user clicks OK, and a different
        tune is selected, a crash (segfault) could occur on Arch.
        So clicking OK now enables quiet mode for the restart, so
        that the remap dialogs does not come up again.
        Let the user be aware!
    -   A similar segfault with the "Unavailable port" message.
        Instead of setting quiet, the better fix seems to
        be stopping the qseqeditframe64 timer before
        the close() call in qseqeditex.
    -   A similar segfault with the "LFO" dialog. Fixed by no
        longer resetting the MIDI events when the close event
        occurs. Holy moly.
-   Pattern editor.
    -   Mitigated issue #144 (painted notes misplaced in time)
        for normal notes and drum notes by added a portion of
        snap to the location of the mouse click. If this is
        still an issue, simply reduce the size of the snap.

## [0.99.23] - 2026-04-15

This version has changes to better support Qt6, better display
and selection of program and controller change events, and
other minor fix-ups.

### Added

-   Event editor.
    -   A new button for either Control or Program changes pops
        up the menus for Control Changes set by the 'usr'
        file and the Program Changes set by the 'patches' file.
-   Added the qchannelpopup class for future refactoring /
    unification of channel menus, but it might never be ready.
    It is in the contrib sub-directory.
-   Instead, added the populate\_midich\_combo() function to the
    qt5\_helpers module, now used in the pattern and event editors.
-   Added the drums module to provide for listings of GM drum
    notes and to support non-GM drum notes display in the future.

### Changed

-   Main window and grid.
    -   At startup, instead of setting argv[0] as app-info. set
        QCoreApplication::applicationFilePath().
    -   Now uses the populate\_midich\_combo() function.
-   Event editor.
    -   Now uses the populate\_midich\_combo() function to show
        the control/program drop-down menus.
-   Palettes.
    -   Updated the incrypt-66.palette file; some colors don't
        apply in the old version.
-   Worked on some Qt6 deprecations.
-   Documentation updated. Additional pictures for Event editor.
-   Moved the LICENSE files to "licenses" sub-directory.

### Fixed

-   Various fixes to controller and patch naming and handling.
-   Fixed Qt6 deprecations.

## [0.99.22] - 2025-10-26

### Added

-   Issue #141, mostly implemented. See "Pattern editor" below.
-   midifile.
    -   Added storage for the first BPM value, needed by performer.
-   Main window and grid.
    -   With the mouse pressed, the current slot holding the cursor
        is drawn "flat".
    -   Giving a grid slot "focus" and then pressing the Menu key
        brings up the grid-slot popup menu.
-   Pattern editor.
    -   Showing note bars for scales and chords:
        -   Added a new brush called "chord" to the palette file.
            Click Edit / Preferences / Session / Store Palette.
        -   When a chord is active, the notes that are _not_
            in the chord are grayed out with diagonal hash lines.
        -   Added buttons to toggle showing the scale/chord bars
            and the filtering of off-scale/off-chord notes when
            painting notes.
        -   Normally the base note of the chosen musical key is
            shown in the keys pane. Undefine the
            SEQ66\_SHOW\_SELECTED\_KEY\_OCTAVE macro to keep
            showing C.
    -   Painting notes in scale/chord:
        -   Added a button to toggle the filtering of notes
            based on scale/chord.
        -   The selected key, scale, and chord determine the
            actual chord represented on the pattern grid.
    -   Added an option to the "Tools" (hammer) menu to select
        notes in a range of pitches. Either note numbers or note
        names can be used. See issue #141 and the user manual.
-   Documentation.

### Changed

-   C++. Added -Wno-unnecessary-virtual-specifier to Clang builds
    to avoid a dumb warning about final classes and virtual
    functions.
-   Pattern editor.
    -   Changed closest-snap to down-snap to make note
        insertion more intuitive.
    -   Removed the redundant display of time signatures in the
        data pane.
    -   We now store the selected chord for a pattern, if any, as a
        new "c\_musicchord" SeqSpec. It is track-specific only,

### Fixed

-   Fixed a segfault at startup on some builds on Arch Linux.
    It seems to have been an issue of order of initialization of
    a static string via a static function.
-   performer.
    -   The file PPQN was set when reading the file, so later the
        set\_ppqn() function would not inform the master bus of
        a PPQN change (in ALSA).
    -   Fixed: the slow playback of high-PPQN files.
-   JACK.
    -   Fixed detect\_jack() and added a missing call to jack\_free().
-   midifile.
    -   Added storage for the first BPM value, needed by performer.
    -   Fixed: Tempo event in track 0 does not override c\_bpmtag
        SeqSpec.
-   Main window and grid.
    -   Fixed: an issue where loading a file with a different PPQN
        raised the modify flag.
    -   Fixed: When dragging a pattern, modify was set before the
        drag was completed. Also could not move another pattern into
        the empty slot.
-   Pattern editor.
    -   Fixed the snap-interval setting for drawing notes.
    -   Fixed a bug where the background sequence was not loaded
        into the piano roll.

## [0.99.21] - 2025-07-28

    This release contains fixes for issues #137, #138, #139, and #140.
    It also contains a number of smaller changes discovered while
    fixing these issues. See below.

### Added

-   Main window and grid.
-   Pattern editor.
    -   Pattern-fix dialog.
        -   Added parameters for randomizing note pitches according
            to the current musical scale for the pattern.
        -   A pitch-randomization function was added to the eventlist.
            The notes adhere to the currently selected musical scale.
        -   Added space above and below the data range and added
            top/bottom lines and value labels. See issue #140.
        -   Adding an Insert macros function to Tools.
    -   LFO. Added a "DC Only" option.
-   Song editor.
-   Event editor.
-   Preferences dialog.
    -   Detection of using ALSA's "Midi Through" ports for both
        control added.
    -   Detection of this at startup has been added. An error message
        is posted and MIDI Control and Display disabled, for safety.
-   Import/Export.
-   MIDI defaults. Added to midibytes.h:
    -   c\_midi\_clocks\_per\_metronome = 24
    -   c\_midi\_32nds\_per\_quarter = 8
-   Documentation.

### Changed

-   A C++17 compiler is now required. Time to move on!
-   Changed eventlist::sort() to use std::stable\_sort(), and
    event::get\_rank() to make CCs and Program Changes to have the
    same priority, as part of fixes for issue #138.
-   Main window and grid.
-   Pattern editor.
    -   Optimized gradient drawing using QLinearGradient members in
        qseqroll instead of auto objects.
    -   Made the drawing of pitchbend data show +- pitchbend
        better, i.e. above and below the midline pitchbend, 0.
    -   Controller events are now recorded when playback is
        stopped. Time is not incremented. (It can be changed in
        the Event editor, if needed.)
    -   Upgraded the LFO editor as per issue #139.
    -   Added an "Insert macro at L" function in the Tools popup
        menu.
    -   Upgraded the MIDI control macro feature to allow multiple
        events in each macro, separated by " | ".
-   Song editor.
    -   Optimized gradient drawing using QLinearGradient members in
        qperfroll and qperfnames instead of auto objects.
-   Event editor.
-   Preferences dialog.
-   Contrib files.
-   Coalescing common code. Also removed the midistring type to use
    midibytes (a vector) instead.
-   Changed the scales\_policy() function slightly.

### Fixed

-   SMF 0 Import. Meta events are now stored in pattern 0.
    See it by loading contrib/midi/CountryStrum.mid.
-   Main window and grid.
    -   The BBT/HMS button tooltip was moved from the qsmainwnd
        widget to the button itself. Doh!
    -   The playlist code was auto-arming all patterns even when
        the playlist was not active.
    -   Changing the main time signature now changes the time
        signature in all patterns (except for those with a pattern
        editor open).
-   Pattern editor.
    -   The drawing of scales was done incorrectly. Fixed both the
        seqroll grid drawing and the scales\_policy() function.
    -   Fixed seqroll 'r' command (velocity randomization) to set
        the modify flag only if (selected) events are actually
        randomized.
    -   Fixed the drawing of "ghost notes" when moving or pasting
        notes.
    -   PPQN updates.
        -   Fixed the adding of painted notes (mostly) at PPQN other
            than the long-standing base default, 192.
        -   Changed the lowest PPQN from 32 to 24, for those who
            experiment. Also added PPQN = 48.
        -   Fixed File / New to reset PPQN to the default (192).
            It also resets the tempo to the value in the 'usr'
            file.
        -   Fixed the handling of the MIDI file PPQN to set initial
            zoom correctly for all supported PPQNs, and when "0"
            is clicked, in the pattern and song editors.
    -   Fixes made to pitchbend calculations and display.
    -   Updated the time-signature handling as per issue #137.
    -   LFO.
        -   When using LFO, saving, then exiting via the main window
            a prompt about a needless save was removed.
        -   Fixing the LFO for operation on pitchbend.
    -   Fixed qeditbase::snap\_x(); removed the PPQN ratio factor.
    -   Modified adding painted notes to the closest tick snap,
        also fixes adding notes while zoomed.
-   Song editor.
-   Event editor.
-   Preferences dialog.
    -   Fixed the enabling/disabling of entries in the control and
        display combo-boxes when changing active status of control
        and display.
    -   A warning is provided when using a MIDI Through port for
        both control and display, which can lead to FIFO overruns
        and weird stuff like segfaults.
-   Configuration files.
-   Classes.
    -   midifile.
        -   The earliest time-signature event, if present,
            overrides the c\_timesig SeqSpec.
        -   SeqSpecs with no data (length == 4) were read improperly.
    -   performer. Changed default 32nds-per-quarter-note from 0 to 8.
    -   sequence. Used the new MIDI default values and fixed an
        index error in add\_timesig\_event(). 
-   Module midifile.
    -   Cleaned up the handling of time signature events and the
        c\_timesig SeqSpec, now set to 4/4 in files saved before
        this fix.

## [0.99.20] - 2025-06-12

### Added

-   Main window and grid.
    -   Clicking on the Seq66 logo in the main window now closes all
        open live grids, pattern editors, and song editor windows.
        The tabbed version are not affected.
    -   Added features to the grid slot popup menu:
        -   Flatten triggers. This uses the pattern triggers to
            regenerate the notes, replacing multiple triggers with one
            long one (may need some work yet). Similar to Song Export,
            but for one pattern, and no export is done.
        -   Export pattern. Saves a single track to a new file, at
            pattern number 0. (May need some work yet).
    -   Control/pitch events now show up in pattern-slot progress box.
        Can be disabled via 'usr' [user-ui-tweaks] progress-box-show-cc
        = false.
    -   A timed error prompt (instead of OK/Remap and restart) when
        running via NSM; see qsmainwnd and qt5nsmanager.
-   Pattern editor.
    -   Added some horizontal dotted lines to the data pane to mark
        the 32, 64, and 96 level (of items such as velocity).
-   Song editor.
    -   Added a dark vertical border at the end of a song.
-   Event editor.
    -   Added display of the pitch-bend in semitones in the event
        editor. It currently assumes a range of +-2 semitones, a
        MIDI default.
    -   A column in the event editor shows the bus number that the
        event came in on. Not saved with the event, however.
-   Preferences dialog.
    -   An ALSA/JACK label to JACK preferences tab, same as in mainwnd.
    -   The button to "Clear" the port-maps has been removed. The
        port maps are always present, but can still be deactivated.
-   Import/Export
    -   Added a 'usr' option to enable/disable automatic conversion of
        an SMF 0 MIDI file to SMF 1.
    -   The export of files to SMF 0. See the "MIDI Import/Export"
        section of the user manual for provisos.
-   Documentation.
    -   Changes, fixes, and additional features in the user manual.

### Changed

-   Main window and grid.
    -   A pattern with a color shows that color even if empty.
    -   Made the button heights uniform in all Qt styles (so far).
-   Pattern editor.
    -   Nested editing and copy/paste menus into Edit and Track
        submenus.
    -   Record indicator supports a gradient brush.
-   Song editor.
    -   Thick line between sets in the song editor.
    -   Thick line at the end of a song.
-   Event editor. No changes; see "Added".
-   Preferences dialog.
    -   Enhanced the recent-file handling and auto-rc-save.
-   Many other minor tweaks to comments and appearance.
-   Contrib files.
    -   contrib/vim-syntax/cpp.vim with added symbols like CSTR.
    -   contrib/vim.rc, changed F8 for fixing Windows quote characters.
-   Coalescing common code.
    -   qsmainwnd.
    -   Sequence recounting after deletion or moving of patterns.
    -   More, did not keep track.

## [0.99.19] - 2025-03-02

### Fixed

-   Issue #136.
    -   Filtered out Program events from the drum-mode piano roll.
    -   Can now drag Program events up and down in the data pane.
        -   While working this issue, the following problems
            were found and fixed.
            -   The saving of Program events was fixed to calculate
                the proper time-stamp.
            -   Program events can be moved up and down by dragging,
                as well as by the line-dragging method.
        -   Added display of the names of Control and Program
            Change numbers in the event editor and pattern editor..
-   Pressing the finger button in the pattern editor now
    also enters paint mode in the event pane. The selected event
    category can the be entered by a click, and then moved up and
    down in the data pane.

### Added

-   This macro is defined by default: SEQ66\_SHOW\_GM\_PROGRAM\_NAME
    to show the GM patch names in the pattern editor data pane
    instead of just the patch/program number. See seq66\_features.h.
-   Added a new configuration file, '.patches' that can be used
    to show non-GM device program names in lieu of the built-in
    GM program name. Also specifiable in the Preferences / Session
    tab.

## [0.99.18] - 2025-02-03

More developer-discovered issues :-(

### Added

-   Added the dark-theme and dark-ui options to the user file for
    handling GUI elements that are otherwise difficult to see.
-   Added an option to dump the current palette while automatically
    inverting to create the --invert palette. It's activated by the
    SEQ66\_PROVIDE\_AUTO\_COLOR\_INVERSION macro.
-   Added a Help / View Log function to bring up the latest log
    text (if a log file is enabled).

### Changed

-   contrib/scripts/jackctl.
    -   Beefed up the jackctl script to facilitate testing.
    -   Added the "-u" option to a2jmidid in the jackctl script, to
        avoid undesirable changes to port names.
    -   Added support for raysession and agordejo.
-   Refactored the copy-configuration and delete-configuration
    functions to make them more robust and less dependent on
    file-extension.  Depends on the SEQ66\_KEEP\_RC\_FILE\_LIST
    macro.
-   Updated the show\_folder\_dialog() function to show hidden
    directories.
-   Disabled the various "Remap"/"Restart" buttons when running
    under an implementation of NSM.

### Fixed

-   Issue #135.
    -   Added an inverse pattern-length icon for dark themes.
    -   Fixed the vertical lines in the time panel so as not to
        obscure the measure numbers.
    -   Updated the pattern-editor piano roll drawing to avoid
        invisible vertical lines. See the dark-theme and dark-ui
        options too.
-   Fixed a seqfault when pressing an empty button on a set other
    than the first set. Also fixed in tag 0.99.17.1.
-   Fixed the JACK-to-ALSA fallback process, broken if the computer
    is running the jackdbus daemon. Also tested were differences in
    a2jmidid between two dev computers.
-   Fixed an error in the --home command-line option that left
    "home" as "~/.config/seq66".
-   Refactored and fixed the Import Project Configuration menu.
-   Refactored and fixed the Export Project Configuration menu.
    It now can locate and copy any PNG files (used in some of the
    Seq66 style-sheets). Currently the copying of PNGs is
    Linux-only [It uses the glob() function].
-   Fixed the route66 bitmap.

### Removed

-   The pattern-fix effect check-box for the "Truncate" effect,
    which cannot occur anymore.

## [0.99.17.1] - 2025-01-12

### Fixed

-   Fixed a segfault when clicking an empty pattern on sets 1 and
    above.

## [0.99.17] - 2025-01-10

This release provides a rather large number of fixes, including bugs
found while investigating user reports. Included are updated palettes
and Qt style-sheets, and a beefed up pattern-fix dialog.

### Added

-   Added a "thick grid lines" checkbox to Edit / Preference / Display
-   Added usage of "Extra" color for line drawing.
-   Added "Align Right" to the Pattern Fix dialog.

### Changed

-   Revamped and extended the functionality of the Pattern-Fix dialog.
    As part of this, the alteration API of the event-list has been
    updated.
-   Refactored vertical grid-line calculations; code moved into the
    zoomer.  For odd time-signatures (i.e. with a beat-width not a
    power of 2, which is not allowed in MIDI but is stored in a
    SeqSpec event in Seq66) we draw fewer lines in between bars to
    make a cleaner display. But do not expect them to be "nice".
    See the 4/7 pattern in the timesigs.midi file.
    -   Pattern editor. Better support for thick vs. thin grid lines.
        -   qseqroll.
        -   qseqtime.
        -   qstriggereditor.
    -   Song editor. Better support for thick vs. thin grid lines.
        -   qperftime.
        -   qperfroll.
    -   qeditbase. Macroed out unused zoom functions. Moved most to the
        zoomer class.

### Fixed

-   Fixed segfault when clicking the Restart button with external live
    frame(s) or external song editor open.
-   Issue #128 follow-on.
    -   Fixed the removal of trailing notes after truncating a pattern
        to a smaller number of measures.
    -   Upgraded one-shot recording to work during playback. Still
        minor issues; see the user manual.
-   Issue #133 and issues found while working this.
    -   Pattern editor.
        -   Changed the slot connection for editable combo-boxes to
            connect the lineEdit() accessor.
            -   Measures (pattern length) combo-box. Also made
                cancelling the change work correctly.
            -   Beats-per-bar combo-box.
            -   Beat-width combo-box.
        -   Fixed a seqfault when opening tune with a pattern-editor
            already up for the current tune. The side-effect is that
            armed status will not synch between the main window and
            the editor.
        -   Fixed raising the modify flag when a second pattern (with a
            different time signature) was opened in the editor.
        -   Fixed a potential segfault when opening a recent file with
            a pattern currently open for editing.  Had to add polling
            to check for changes in arm status. 
        -   Refactored the event/buss dropdowns to be modified only when
            the user changes setting or tries to bring up the dropdowns
            (lazy dropdowns).
    -   Song editor. Time zoom now affects horizontal scroll-bar length.
-   Issue #134. Added dates to the release-name line from 0.99.14 on;
    were left off by an oversight.
-   Pattern-fix editor. Somewhat revamped, many fixes made, and more
    testing done.
-   Non-standard time signature handling errors. Note that we cannot
    support non-power-of-2 beat-widths well in the piano-rolls.
-   Main window. Fixed updating the PPQN when a file of different PPQN
    is loaded.
-   Cleaned up and upgraded the linking of recorded notes.
-   Made ghost notes in selection box official. Also made it apply
    to select-all and other selection operations.
-   Fixing and normalizing the functionality of the Pattern-Fix dialog.
-   Fixed timestamp setting in opening the event editor for empty
    pattern.
-   Some minor tweaking (field size, font) of various dialogs.

### Removed

-   Nothing. Maybe a few unnecessary macros.

## [0.99.16] - 2024-12-03

This release provides fixes to user issues and a ton of related
fixes found while investigating the user issues. Some minor new
features added.

### Changed

- Documentation. Refined discussion about the about the Import/Export
  functionality, and some of the minor additional features. Some new
  screenshots still needed.
- Build configuration. Added CONFIG\_DIR\_NAME and cleaned up
  configure.ac. Updated the Makefile sources.
- Merged a fix from a pull request (issue #130) to correct
  the \*.desktop files.
- Pattern editor.
    - Renamed [new-pattern-editor] to [pattern-editor] in the 'usr'
      file. Also added the "Apply to new only" option to Edit /
      Preferences / Display.
    - The Quantized Record button in the pattern editor now goes through
      this sequence when clicked: None, Tighten, Quantize, Notemap,
      None.... Also prettied-up the icons.
    - Enhancements to pattern-editor note copy/paste:
      - The paste-selection box now shows the selected notes,
        ghosted, for easier placement.
      - A right-click cancels a paste action in the pattern editor.
    - Undid a change from awhile back that broke the recording of
      fast-keyed notes on the same MIDI key. Still need to fix the
      occasional zero-length note.
    - Added provisional code to speed up recording. Grep for the macro
      SEQ66\_LINK\_NEWEST\_NOTE\_ON\_RECORD. Has potential issues, so
      it is undefined.
- Color palette. Added access functions for "scale" (new) and "extra"
  colors in the palette, to improve the coloring (e.g. of the bars
  denoting notes in the scale of the pattern editor) in certain Qt
  style-sheet usages.
- Event editor. Enhanced writing pattern-dump files from the event
  editor.

### Fixed

- Issue #128.
  - Expanded recording.
    - Is now working. The expansion is continual, not waiting for a
      MIDI key to be struck. Also see the changes to the record
      buttons in the pattern editor.
-   Click-drag drawing of notes with "expand" set now works.
- Issue #130. Merged a pull request for issue #130 to fix the
  \*.desktop files.
- Issue #131. NSM interaction errors introduced in version 0.99.11,
  plus other related issues:
  - The NSM would show two clients: "qseq66" and "seq66" when adding
    only the "qseq66" client.
  - Saving via a remote NSM Save command or by the File / Save menu
    would not clear the modified flag.
  - Closing the session would not remove any external editor windows.
- Automation. Some automation actions need to work whether the action
  is "on" or "toggle". Fixed these 'ctrl' actions:
  - Save session (under NSM) or the MIDI file.
  - Record style select.
  - Quit.
- Pattern editor.
  - Fixed the display of tunes with various PPQNs such as 120 and 240.
  - Fixed zero-length notes caused by quantized recording.
  - Fixed the pattern editor so it reflects buss and channel settings
    made from the grid slot popup menu.
- Main window.
  - Fixed the following scenario: Load a song; do File / New; make a
    pattern; then File / Save. It overwrites the previous song. The
    fix now brings up a prompt for the name of the new file.
  - The main window now reflects the current record-loop style and
    new-pattern option as read from the 'usr' file.

### Added

- Main window.
  - Added "Clear events" to the grid slot popup menu. It keeps the
    pattern in the slot, but removes all of its MIDI events.
  - Added 120 PPQN to the list of supported PPQNs.
- Build configuration. Added a "config directory" macro to
  configure.ac and seq-feature functions to access it. Differentiates
  between client and directory name.
- Added monogreen.palette, monogreen.qss, and a down.png icon. Copy
  all to ~/.config/seq66 and modify the image url in the qss file
  to match your setting. Will work on a qrc file for a future release.
- 'usr' configuration file. Currently must edit the file to change
  these values.
  - progress-bar-thickness. Changes the width of the progress bars
    if progress-bar-thick = true. It mainly affects the song editor.
  - gridlines-thick. Paints the normal song editor grid. If false,
    then more lines are thinner or dotted; useful if the foreground
    color is bright. It mainly affects the song editor.

## [0.99.15] - 2024-10-28

### Added

- Added edit fields and buttons for selecting a non-default browser
  or PDF viewer to the Preference's Session tab.

### Fixed

- Some font handling in the various tabs and windows.
- Cleaned up the configuration dialogs.
- The file-selection dialog(s) when no file-extension is used.
- An error in getting the name of the mutes file in the Preference's
  Session tab.

### Changed

- Updating configure.ac to disable, and not allow enabling, of JACK,
  NSM, and liblo (OSC) if libraries not installed.
- Progress made getting a build to work in MSYS2. Not yet ready.
- Built on Windows 11 with a update to Qt 5.15.2 and mingw 8.10.

## [0.99.14] - 2024-08-14

### Added

- Added the use of the Esc key to close the external song editor window
  if not playing and not in adding mode. Similar to the fix made to
  the pattern editor for issue #117.
- Added the elliptical progress-box option to Preferences / Display.
- In the pattern editor, a tiny unlabelled button toggles the
  showing of note information when the mouse hovers over a note.
- Added a note-tooltip option. Click the unlabelled button at the left of the
  horizontal scroll-bar. Then hovering over a note shows some note information.

### Fixed

- In the zoomer class, rearranged members to avoid a warning (error)
  from g++ v. 14.2.1 about zoom being uninitialized in the constructor.
- Issue #128 "Recording type for loop button not working". Fixes the
  Issue in both directions.
- Issue #129 "Quantized Record Button problem" fixed by allowing
  the existing sequence recording status to be modified with an alteration.
- Tightened up the handling of selecting a pattern's input buss.

### Changed

- Standardized on "Overdub" for the pattern-window merge functionality.
  See issue #128.
- Updated the PDF documentation based on issue fixes and other fixes.
- Replaced the --session-tag option with --session.
- Changed the sort order of MIDI events so that Note Offs get priority over
  Note Ons with the same time-stamp. Prevents playback errors in
  the tune judyblue.mid. Enabled via macro SEQ66\_PRIORITIZE\_NOTE\_OFF.

## [0.99.13] - 2024-08-05

    This release is minor, a couple of lesser feature and some fixes.
    No release files are provided, no Windows installer. We've been
    working on another project, and it is time to move forward here.

### Added

- Added 'progress-box-elliptical' to the 'usr' file.
  It is a 'usr' option to show an elliptical progress box.
- New license files adhering to GitHub conventions.

### Fixed

- Fixed the writing and byte-counting of the end-of track event.
  This adds 1 byte to the size of a Se66 MIDI file.
- Fixed the counting of the size of empty note strings. Empty notes
  alway have a two-byte (short) note length of 0.
- A segfault would occur when opening a pattern from a second song
  while the pattern editor from the first song was open.

### Changed

- Changed the Tempo Track setting fields slightly in Edit / Preferences
  for clarity.
- Added more robust handling of the Seq66 SeqSpec track. This is the final
  track in an Seq66 MIDI file, and is not counted. But some applications
  might count it as a track when saving the MIDI file.
- In sequence::play() we now put SysEx events on the output bus.

### Removed

- Removed LICENSE and the licensing text files it refers to.

## [0.99.12] - 2024-01-13

### Added

- Clang compiler support.
- Provisional build process for FreeBSD.
- Added an autogen.sh script to reconfigure without using bash.
- Added 'rc' option to skip, recover, or abort from bad running
  status in MIDI files (trilogy.mid).

### Fixed

- Errors and warnings revealed by Clang.
- The reading, processing, writing, and display of SysEx and Meta
  events. Now handle unterminated SysEx messages (Dixie04.mid).
- Issue with building the command-line "portmidi" version.
- A one-character buffer overflow in portmidi.c.
- Bugs in --option log=file.
- Q button not working to set keep-queue status.
- Queued-solo functionality improved.

### Changed

- Upgraded the Event editor Dump output.

### Removed

- Disabled the grid-solo option as redundant. Will repurpose later.

## [0.99.11] - 2023-12-04

### Added

- Added 8 more ui-palette entries, total of 32. Probably enough.
- Added display of a pattern input bus (if present) in the grid
  slot. It is shown just before the pattern length at top right.
- Added mute-group label ("MG") to main window.
- Added a pre-made MIDI file to use with record-by-channel.
- Added a record-by-buss feature.
- Added a way to toggle recording of more than pattern at once.
- Can now paste a pattern into a new or another loaded MIDI file.
- Added optional paramater to the --priority option.
- Added showing program changes in slot button.
- Added showing text events in the data pane and all text events
  in the main Session tab. Fixed its Save Info button.
- Implemented the "menu-mode" automation. It duplicates the function
  of the hide/show button, to toggle between hiding some of the main
  window controls and the main menu, and showing them.

### Fixed
  
- Issue #123 "Would it be possible to have NEWS structured like a
  changelog"
- Fixed errors setting style-sheet, palette, and mutes in
  Preferences / Session.  Enhanced this tab to indicate when
  exit (as opposed to internal restart) is needed.
- Fixing various playlist errors:
  - PPQN setting issue causing slow/fast playback. Cannot
    display 120 PPQN well, fix too intrusive. Converted
    contrib/midi/Carpet_of_the_Sun_karaoke_meta_text.mid
    from 120 to 192 PPQN.
  - Segfaults due to not stopping playback before loading
    the next song or basing calculations on missing values.
- Fixing the massive botch of the Set Master tab.
- More fixes in Mutes tab, including raising the modify flag.
- Fixed app exiting unceremoniously if "quiet" is set.
- Fixed minor issue in Song zoom with 1920 PPQN.
- Fixed odd bug breaking MIDI-control-out (display).
- Prevent long redundant start-up error messages.
- Fixed solo feature. Should unsolo before starting another
  solo.
- Fixed queue and keep-queue.
- Fixed not saving record-by-channel. Fixed record-by-channel.
- Prevent long redundant start-up error messages.
- Fixed solo feature. Should unsolo before starting another
  solo.
- Fixed queue and keep-queue.
- Fixed not saving record-by-channel. Fixed record-by-channel.
- Fixed not modifying the song when pattern measures is changed.
- Fixed breakage of stopping song play at the end of song.
- Fixed bug in event-editor initialization.
- Fixed not applying note-length setting to step-edit.

### Changed

- Moved style-sheet options from 'usr' to the 'rc' file. Upgrade
  is automatic.
- Improved copy/paste for screen-sets in the same way.
- When loading a MIDI file, the file dialog defaults to the
  last-used directory. Fixes made to this feature.
- Focus is now set immediately to the seqroll and perfroll.
- Replaced some verbose() checks with investigate() checks to cut
  down on console output. In the CLI, --verbose now shows
  playlist actions on the console and prevents daemonization and
  logging to a file.
- Replaced the --inspect option with --session-tag to allow easy
  changing to another setup specified in sessions.rc. Also added
  the SEQ66_SESSION_TAG environment variable.

### Removed

- No removals.

## [0.99.10] - 2023-10-25

### Added

- Added drag-and-drop of one MIDI file onto the Live grid.
- Added the export of most project configuration files to another
  directory.

  in the Live Grid.  The default group-selection keystroke is "\_".
- Added feature to scroll automatically in time and note value
  to show the first notes in a pattern.
- Added more UI palette items for more non-Qt color control.
  Modified the inverse color palette slightly. Added checkmark
  for the active pattern color in its popup menu.

### Fixed

- Issue #117 Option to close pattern windows with esc key. Must
  be enabled via a 'usr' option first.
- Issue #118 Make virtual ports ports enabled by default.

- The live-grid record-mode and alteration statuses are now applied
  when the pattern editor is opened. The "Record toggle" popup
  menu entry and MIDI control also support this functionality.
- Tightened the file-name/activity handling in Session preferences.

### Removed

## [0.99.9] - 2023-09-24

  code.
- Implemented automation for BBT/HMS toggling, FF/Rewind, Undo/Redo,
  Play-set Copy/Paste, and Record Toggle.
- Added a build-time option to add a show/hide button in the
  main window to allow making the window to take up much less space.
- Added HTML help files to data/share/doc/info, other documentation
  upgrades.

## [0.99.8] - 2023-08-27

- Issue #112: A new pattern now displays in the MIDI controller.
- Issue #114: Adding display of shortcut keys to tool tips.
- Added a Pattern tab to Edit / Preferences for new-pattern settings
  and jitter/randomization.
- Added automation for the main window Loop L/R button.

## [0.99.7] - 2023-07-19

- Issue #110 follow-ons:
  Cannot save tempo (BPM) in Windows when
  changed from main window. Caused by mixing a long and size_t,
  which messed up in the Windows build.
- Issue #111 follow-ons:
  - Fixed initial time-signature drawing in data pane.

    calculator that iterates through time-signatures.
- Fixed an important port-translation bug in output port-mapping.
- Recent Files is disabled if there are none.
- Revamped the Playlist tab, as it was confusing and very buggy.
- Added Windows key-mapping to fix processing "native virtual" keys,
  such as the arrow keys. Also fixes issue #102.
- Added auto-play and auto-advance to play-lists.
- Fixed bug in rcsettings::make_config_filespec().

## [0.99.6] - 2023-07-01

  - Fixed issues with port-mapping and the Windows MIDI Mapper.
  - Issue: Building 32-bit (Windows XP) version on 64-bit Windows.
    On 64-bit Windows, this seems to require building a 32-bit
    version of the Qt toolset. Ugh.
- Issue #111: Adding support, as much as possible, for editing,
  storing, and displaying time signature in the pattern and event
  editors.
  - The first time-signature in a pattern becomes the main
    time signature of the pattern. (Also stored as a c_timesig
    SeqSpec).
  - The data pane shows a time-signature as a simple fraction.
  - Changing the time signature if at time 0 is automatic.
  - Time signatures at later times can be logged by setting the
    current time with a click in the top half of the time line,
    changing the beats and beat width, then clicking a time-sig log
    button.
  - Time-signatures with a beat width that are not a power of 2
    do not add an event, but are saved as the c_timesig SeqSpec
    value.
  - Provisional feature: we properly draw the piano roll, time line,
    event pane vertical lines as time-signature changes.
  - Fixed event filtering in the event (qstriggereditor) pane.
  - Fixed time-signature editing in the event editor, and the
    B:B:T to pulses calculation.
- Enhanced port-mapping to prompt the user about issues and
  allow for an immediate remap-and-restart. A ton of fixes!
- Added 'o' keystroke to seqroll to toggle recording ('r' already
  used to randomize notes).
- Added a "quiet" option to not show startup message prompts.
- Enhanced the Edit / Preferences dialog.
- At first start, a log-file is now automatically created. If it
  gets larger than a megabyte, then it is deleted to start over.
- Fixed bug writing pattern-dump files from event editor.
- Improved modification detection and display in the pattern editor.
- Added the pattern port number to the song summary output.
- Updated alsa.m4 to avoid obsolete AC_TRY_COMPILE warning. Old
  version stored in contrib/scripts.

## [0.99.5] - 2023-05-20

- Greatly enhanced the event editor tab and the events that can
  be view and modified.
- Made port-mapping the default. At first startup the map
  exactly matches the existing ports; the user can edit this setup
  in the 'rc' file or the Preferences dialog.
- Eliminated "missing ctrl" message at first startup.
- Fixed port ID setting in midibus, and adding output flag in
  midi_alsa_info.
- Issue #110 Windows: Fixed compiler errors and added scripting to
  build NSIS-based install without leaving Windows, if desired.
- Internal refactoring to regularize handling of the session/config
  directory between Linux and Windows.
- Fixed portmidi bugs in Linux and Windows, enhanced device naming.
- Showing disabled/unavailable MIDI devices as grayed in various
  dropdowns.
- Rearranged the Seq66 man pages more sensibly.

## [0.99.4] - 2023-04-30

- Issue #3: The scroll wheel is enabled in the piano rolls (only).
- Issue #48: For a new NSM session configuration, disable "JACK"
  port auto-connect.
- Issue #108.  Fixed trying to remove Event tab after deleting it.
- Issue #109.  Fixed the application of channels to the various
  export operations.

- Fixed drawing of wrap-around notes with linear gradient, and fixed
  handling of note wrap-around when set to false.
- Fixed refresh of Mute and Session tabs when loading a MIDI file.
- Added seqmenu entry for toggling recording of a pattern.
- Added the ability to use the first Text message as "song info".
- Seq66 now prevents opening the event editor if recording is in
  progress. Cannot update event editor live with new events.

## [0.99.3] - 2023-04-19

- Issue #107.  The basic fix is made. Still need to rehabilitate
  the Expand-pattern functionality.
- Issue #40.  Improved NSM handling:
  - Seq66 detects nsmd as the parent process early in startup.
  - Close ("X") button disabled and hidden.  Xcfe4 "close window"
    action works, though, as does response to a SIGTERM from nsmd.
  - Handling "config" subdirectory improved.
  - The --nsm option is now for debugging only, simulating running
    under NSM.
- Automation fixes:
  - Fixed processing grid keystrokes twice.
  - Renamed record-mode and grid-model control labels.
  - Fixed accident disabling of grid-mode controls.
  - Making MIDI control-out handling more reasonable.
  - Added some LaunchPad Mini macros.
- Added reading/writing/displaying Meta text events such as Text
  and Cue Point.
- Fixed broken "recent-files" features (by forcing 'rc' save).
- Improvements made to playlist handling. It wasn't displaying
  the BPM of the next tune.  Still have issue with the BPM spinbox
  not causing a file modification. Editing the BPM works.
- Improvements and important fixes to mute-group and its MIDI
  control still in progress.
- Fixed the daemonization and log-file functionality.
- Revisited the recmutex implementation.
- Weird error where ALSA not found! We now avoid a crash, but
  qseq66 currently exits with only console messages.

## [0.99.2] - 2023-03-04

- Issue #103.  Some improvements to pattern loop-count.
- Pull request #106. User phuel added checkmarks for active buss and
  channel in grid-slot menu.
- Fixed background sequence not displaying when running with
  linear-gradient brush.
- Fixes to brushes and making the linear gradient (notes and triggers)
  a default run-time option.  See the 'palette' file.
- Other minor fixes and documentation updates, including the manual,
  as per issue #104.

## [0.99.1] - 2022-11-27

- Issue #44. Revisited to fix related additional issues. Can now
  toggle a pattern's song record in perfnames. Record button:
  Ctrl disables snap, Shift enables record at playback start.
  Still minor issues.
- Issue #93. Revisited to fix related open pattern-editor issues.
- Issue #100. Partly mitigated. Added a custom ringbuffer for MIDI
  message objects to replace JACK's ringbuffer. Adapted work from
  the ttymidi.c module.  Also added configuration to
  calculate the sample offset.
- Various fixes:
  - Fixed partial breakage of pattern-merge function.
  - Fixed odd breakage of ALSA playback in release mode.
  - Fixed Stop button when another Master has started playback.
  - Shift-click on Stop button rewinds JACK transport when running
    as JACK Slave.
  - Display of some JACK server settings in Edit / Preferences.
  - Fixed handling of Ctrl vs non-Ctrl zoom keys in perfroll.
  - The pernames panel now matches the layout of a grid button
    better.  Other cosmetic changes.
  - Event-dump now prompts for a text-file name.
- Added linear-gradient compile-time option (seq_features.h) for
  displaying notes and triggers. Enabled by default, edit to disable.
  Does not seem to add noticeable overhead.

## [0.99.0] - 2022-09-03

- Issue #44. Record live sequence changes functionality beefed up
  to handle recording without snapping.
- Issue #54. Updated the ax_have_qt_min.m4 file to detect
  qmake-qt5, etc.
- Issue #78 revisited. Pattern-box sizes would become 0 and the
  progress boxes disappear. Now the 'usr' show option is boolean
  ("pattern-boxes-shown", default = true), and the sizes are kept
  within reasonable limits.  Also added a "--locale" option so that
  the user can, for example, set the Seq66 global locale to
  "en_US.UTF-8".
- Issue #82 allows buttons and fields to expand better.
  Fixed for main window and the song & pattern editors only.
- Issue #89 fixed. The MIDI control display not quite reflecting the
  status of each pattern, especially during queuing.
- Issue #90 improvements. Save was not always enabled. Surely some
  issues remain.  Also, in some cases there is no way to "unmodify".
- Issue #93 fixed. The window of a deleted pattern now closes.
- Issue #94. Long song in song editor could not be scrolled to the
  right.  Added more padding and a button to expand the grid when
  when desired. For the pattern editor, the workaround is to increase
  the "length" in the pattern editor.
- Issue #97. Investigate/resolve differences from Seq24.
  - Pattern editor fixes.
  - Added paste box when pasting notes, an oversight from the Seq24
    reboot.
  - Added Ctrl-Left/Right to move the progress bar in the pattern
    editor. (Left/Right scrolls the piano roll.)
- Issue #98. Feature requests (metronome and background recording).
  - Added an initial metronome facility and 'rc' configuration.
  - Metronome count-in added.
  - Background automatic recording added.
- Various fixes:
  - Muted pattern slots show a short progress bar, to aid in the
    timing of queuing.
  - Improved the handling of the MIDI 'ctrl' file and control
    states upon a restart.
  - Tightened up pattern arming/disarming processing.
  - Implemented left/right arrow keys to move the selected trigger
    in the song editor. Ctrl moves multiple triggers. Moving a
    trigger past END moves END.
  - Fixed error in painting tempo events in triggers (perfroll).
  - Improved keystroke movement of "L"/"R" markers in song and
    pattern editor time bars.
  - The global time signature is now applied to new patterns.
  - Added a try-catch to showing the locale.
  - Ctrl-Z removes all mouse-painted notes at once (like Seq24).
    Single-note removal is macroed out.
  - Error in parsing "--option sets=RxC" fixed.
  - Improved the handling of grid font sizes re window size.
  - Fixed the response to incoming MIDI Continue.
  - PPQN != 192 : handle snapping when adding notes; bugs in
    perfroll and perftime.
  - Implement clear-events and double-length grid modes.

- Revisited issue #83, improved GUI editing of control/display
  automation.
- Fixes for issue #87: segfault due to mute-group on larger set-sizes,

  Also fixed out-of-source builds and removed function call tracing.
  Streamlined the bootstrap script; it was always "configuring".
- Changed the Apply button from Edit / Preferences to a Restart
  button.  Further tightening of change detection.
- Moved midibyte/midiboolean functions from strfunctions to midibytes
  and mutegroup. Much header-file cleanup. Do a --full-clean!

  quantized, and changed in length all at once. Useful for fixing a
  badly played pattern or scaling the duration.
- Fixed the issue of leftover child windows of qseqeditframe64.
- Removed odd beat-widths from time signature dropdowns.  Can
  still enter odd values manually, but unsupported by MIDI format.
- Refactored drop-down lists to use the settings module.
- Tightend string_to_xxx() functions and replaced the std::stoxxx()
  functions to avoid throwing exceptions.
- Trying to get rolls, time, data, and event panes to line up no
  matter what the Qt theme is. Difficult.

  the tempo via a tempo event.  Still thinking about MMC.
- Fixed old bug in showing note events; they were filtered by the
  pattern-configured channel!
- Tweaks to style-sheet handling.
- Fixed misuses of msgprintf(). Other minor bug fixes.
- In a new NSM session, do not load the most-recent MIDI file, even
  if specified in the imported configuration.  Also, no longer do an
  automatic import of the home configuration to the NSM configuration.
  Instead, use the "File / Import / Import Project" menu entry.
  See the user manual for how this works.
- Added a "File / Import / Import Playlist" command.
  See the user manual for how this works.
- Made virtual port names in ALSA more consistent. Also create the

  status of the port-map, which is copied to the matching port.
- Fixes in song-editor set-names display.
- Removed unused module qskeymaps.

## [0.98.0] - 2021-12-11

- Fixed issue #41 "Hide Seq66 on closing window" via a "visibility"
  automation command and by fixing the response to "hide/show"
  messages from NSM. Note that the NSM API permits the "Quit" command
  to exit the application. Also see the comments at issue #64 "NSM: UI
  show up after restarting the app".
- Fixed issue #73 "Compile error because of jack_get_version_string"

## [0.93.2] - 2021-05-14

- Changed the mute-group format inside the MIDI file to use a much
  less disk space (about 3K less).  Can be set in the 'rc' file to
  write the old format.
- Minor tweaks to the transposed-trigger functionality.  Can be set in
  the 'rc' file to write the old format.
- Removed the code for the essentially unused Seqtool application.
- Removed the now unnecessary old-style qseqeditframe.
- Add 'usr' tweaks options to change the size of the live-grid
  progress boxes, or eliminate them completely.
- Refactored keymaps for better progress on issue #47, using native
  key-codes. Added a spreadsheet listing the supported names of the
  keys.  Laid the groundwork for a 'keys' mapping file.
- Removed excess spurious events when Seq66 shuts down under JACK.
- Implemented the control-toggling of "follow JACK transport".
- Fixed a bug in the pattern editor that created unnecessary empty
  screen-sets.
- Further fixes and flexibility for handling mute-groups.
- Fixed the installation of libseq66 and libsession library header
  files in "make install" to preserve their base subdirectories.
  (The other libraries currently do not use base subdirectories.)

## [0.93.1] - 2021-05-03

- Work in progress on issue #47; added a keyboard-layout option to the
  'ctrl' file to disable auto-shift and tweak the internal key-map for
  some keyboards.  Added an "AZERTY" 'ctrl' file to the installation.
- Improved group-learn key control.
- Fixed issue #49, mute-group issues, plus a bug in saving mutes to
  the MIDI file.  Added a couple more flags to the 'mutes' file.
- Fixed issue #50, made the slot text color the same as the label
  color, and provided a "secret" default color that will cause the
  text to match the theme.  This can be overridden by a palette file.
- Fixed issue #51 (show-stopper!), where playback with JACK transport
  enable was extremely erratic on some platforms.
- Add clearing of the performer "play-set" for "File / New" to
  prevent the previous song from being playable. :-D
- Activate usage of (larger) seqedit frame in the "Edit" tab via
  a 'usr' option.  Adapted the size to better fit, but the user still
  needs to increase vertical dimension slightly to see the bottom
  buttons.  Will eventually eliminate the old version of the tabbed
  Edit frame.
- Fixed a bug in drawing notes as a new one is recorded; needed to
  "verify-and-link".
- Added a loop-count for live playback of a pattern.  0 means normal
  infinite looping; 1 means "one-shot"; and higher numbers will work.
  Stored with the pattern in the MIDI file.

## [0.93.0] - 2021-04-16

- Added a transpose value to song editor triggers to support shifting
  patterns automatically during Song play.  Added an 'rc' option to
  save MIDI files using the original triggers.
- Improved the song editor vertical scrollbar, it adjusts to the
  number of actual sets.
- Added the L/R marker feature to the external pattern editor, and
  Song mode is no longer required to use it.  This makes it easier
  to explore a long pattern for extracting to a short pattern loop.
- Added more perfroll snap options, including one to force Seq24
  behavior.
- Make the perf-names now also show the pattern color. They highlight
  as the mouse moves over the pattern rows, useful for long songs.
- Fixed playback of ultra-long patterns due to not sleeping in the
  output loop (forgot to convert milliseconds to microseconds).
- Fixed vertical zoom in the pattern editor.
- Fixed a bad bug in writing Meta and SeqSpec data-lengths greater
  than 127.
- Enhanced the event editor to work with channel-less tracks.
- Added channel and bus menus to the grid-button popup menu.

## [0.92.2] - 2021-03-27

- Added a Qt "style-sheet" configuration it to the 'usr' file. It
  can be used to alter the appearance of the application beyond what
  a palette can do.  A sample 'qss' file is provided.
- Fixed PPQN modification, added user-interface and 'usr'
  configuration to change the default PPQN from 192.
- Fixed many issues with changing the time signature.
- Fixed creation of new configuration files.
- Fixed port-mapping for MIDI output, control, and status display.
- Removed the external set-master; use the set-master tab.
- Tightened meta-events and set-handling.
- More fixes to Song recording; added a Snap button for it.
- Fixed the rendering of the beat indicator and pattern fonts.
- Updated the man pages and the documentation.

## [0.92.1] - 2021-03-07

  when there are many ports on the system; also increased port
  limits to 48 ports.
- Fixed issues with iterating through MIDI events in the
  user-interfaces.
- Big fixes to Song recording. More to do?
- Added an experimental one-shot auto-step step-edit feature for
  recording (for example) drumbeats from MIDI devices.
- Fixed bug in parsing Fluidsynth port names.
- Improved handling of MIDI I/O control of Seq66.  Added more
  automation-display events, more testing.
- Updated documentation, including a ODF spreadsheet for the MIDI
  control configuration of the Launchpad Mini.

## [0.92.0] - 2021-02-13

- Fixed issue #34: "seq66 does not follow jack_transport tempo changes"
- Fixed issues with applying 'usr' buss and instrument names to the
  pattern-editor menus.
- Fixing serious issues with the event editor. Now deletes both
  linked notes.
- Added mute-group-out to show mutegroups on Launchpad Mini buttons.
- Tightened up mute-group handling, configuration file handling,
  play-list handling, and MIDI display device handling.
- Stream-line the format of the 'ctrl' file by removing columns for
  the values of "enabled" and "channel".  Will detect older formats
  and fix them.
- A PDF user manual is now provided in the doc directory, installed
  to /usr/local/share/doc/seq66-0.92 with "make install".
