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; control/status via MIDI automation for live performance. Mute-groups enable/disable sets of patterns. Supports the Non/New Session Manager; can also run headless. Works in a space as small as 450x340 pixels (if window decoration removed). It does not support audio samples, just MIDI.
Seq66 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. Also included is initial work on getting Seq66 to build and run in FreeBSD using the Clang compiler.
* Qt 5 (cross-platform). Loop-button gird. Qt style-sheet support.
* Drag-and-drop a MIDI file onto the main grid to load it.
* 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.
* Extremely resizable.
* 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`
* Supports configurable PPQN from 32 to 19200 (default is 192).
* Transposable triggers to re-use patterns more comprehensively.
* Song import/export from/to stock MIDI (SMF 0 or 1).
* Highly configurable MIDI-based metronome.
* Improved non-U.S. keyboard support.
* Many demonstration and test MIDI files.
* See the **NEWS** file or **RELNOTES**.
* 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.
As per Issue #123 "Would it be possible to have NEWS structured like
a changelog", the recent changes now appear at the top of the NEWS file.
