Seq66: MIDI sequencer/live-looper with a hardware-sampler grid interface; pattern banks, triggers, and playlists for song management; scale and chord aware piano-roll; song layout for creative composition; and control/status via MIDI automation for live performance. Mute-groups enable/disable multiple patterns at once. Supports the Non/New Session Manager; can also run headless. Works in a space as small as 725x500 pixels (less if window decoration removed). It does not support audio samples, just MIDI.
Seq66 is a major refactoring of Sequencer64/Kepler34/Seq24 with modern C++ and new features. Linux and Windows users can build this application from source code. See the extensive INSTALL file. Includes a comprehensive PDF user-manual.

The release now includes an installer for the 64-bit Windows version of Seq66.
* Qt 5 (cross-platform). Loop-button gird. Qt style-sheet support.
* Tabs and external windows for patterns, sets, mute-groups, song
layout, event-editing, play-lists, and session information.
* Low-frequency oscillator (LFO) to modify continuous controller
and velocity values.
* A "fixer" for expansion/compression/alignment of note patterns.
* Colorable pattern slots; the color palette can be saved and modified.
* Horizontal and vertical zoom in the pattern and song editors.
* A headless/daemon version can be built.
* Supports configuration files: '.rc', '.usr', '.ctrl', '.mutes',
'.playlist', '.drums' (note-mapping), '.palette', and Qt '.qss'.
* Separates MIDI control and mute-group setting into their own files.
* Unified keystroke and MIDI controls in the '.ctrl' file; defines MIDI
controls for automation/display of Seq66 status in grid controllers
(e.g. LaunchPad). Sample '.ctrl' files provided for Launchpad Mini.
* Support for NSM/New Session Manager, RaySession, Agordejo....
* Handles starting, stopping, hiding, and session saving.
* Displays details about the session.
* ALSA/JACK: `qseq66` using an rtmidi-based library
* Command-line/headless: `seq66cli`
* PortMidi: `qpseq66`
* Windows: `qpseq66.exe`
* Transposable triggers to re-use patterns more comprehensively.
* Song import/export from/to stock MIDI (SMF 0 or 1).
* Improved non-U.S. keyboard support.
* Many demonstration and test MIDI files.
* See **Recent Changes** below, and the **NEWS** file.
* More consistent use of modern C++, auto, and lambda functions.
* Additional performer callbacks to reduce polling.
* A ton of clean-up and refactoring.
Seq66 uses a Qt 5 user-interface based on Kepler34 and the Seq66 rtmidi (Linux) and portmidi (Windows) engines. MIDI devices are detected, inaccessible devices are ignored, with playback (e.g. to the Windows wavetable synth). It is built easily via GNU Autotools, Qt Creator or qmake, using MingW. See the INSTALL file for build-from-source instructions for Linux or Windows, and using a conventional source tarball.
* Version 0.99.6:
* Issue #3 follow-ons:
* Added a qscrollslave to allow QScrollArea to allow the pattern
editor panes to remain in sync with the seqroll when using the
hjkl, arrow, and page keys.
* Issue #110 follow-ons:
* Addition of Start menu entries for Windows.
* Fixed access to the tutorial and manual. Refactored access
to manual and tutorial for robustness.
* Added data/readme files and doc/tutorial files accidentally
left out of NSIS installer.
* Fixed the saving of modified tempo changes.
* Fixed event::is_desired(), which affected changing note
velocities in the pattern editor's data pane. Improved
velocity-change undo.
* Fixed an error preventing changing the "background" pattern.
* 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.
Currently compiled in via a macro (see INSTALL).
* 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.
* Version 0.99.5:
* 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.
See the "NEWS" file for changes in earlier versions. Some proposed features
will be pushed off to Seq66v2; see the bottom of the TODO file. Version
2 is probably a year or two away :-( So many things to improve!
