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, and mute-groups to enable/disable sets of patterns. Tools for live performance and for composing great-sounding MIDI tracks. Supports the Non/New Session Manager; can run headless and on a small computer like the Pi. It does not support audio samples, just MIDI.
Seq66 Seq24/Kepler34 on steroids with modern C++ and new features. Linux and Windows users can build this application from source code. See the extensive INSTALL files. Includes a comprehensive PDF user-manual. As of this release, employs the Meson build system.
The current development-in-progress branch is now "Meson". Seq66 now builds using Meson, and supports Qt6. Bootstrap and build now done via the work.sh script. The old-style build setup is preserved in branch "Autoconf." The lib66 library project is downloaded automatically as a Meson subproject.
The release includes an installer for the 64-bit Windows version of Seq66. Initial work has been done on getting Seq66 to build and run in FreeBSD using the Clang compiler. A C++17 capable-compiler is needed.
See NEWS for updates and RELNOTES for the latest highlights. See the two "INSTALL" files for installation.
The figure below shows Seq66 with modified palette and a style-sheet in force. Otherwise the application uses the current Qt theme.
* Qt 5 or Qt 6 (cross-platform). Loop-button grid. Qt style-sheet
support.
* Colorable pattern slots; the palette can be saved in a '*.palette' file.
* 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.
* Horizontal and vertical zoom in the pattern and song editors.
* Extremely resizable.
* A headless/daemon version can be built to use with a MIDI grid
controller.
* Supports configuration files: '.rc', '.usr', '.ctrl', '.mutes',
'.playlist', '.drums' ('.notemap'), '.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.
* Meson:
* ALSA/JACK: `qseq66` using an rtmidi-based library
* PortMidi: `qseq66` using a portmidi-based library
* Command-line/headless: `seq66cli`
* qmake:
* 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.
* Management of scales, keys, and chords.
* Improved non-U.S. keyboard support.
* Many demonstration and test MIDI files.
* More consistent use of modern C++, auto, and lambda functions.
* Additional performer callbacks to reduce polling.
* A ton of clean-up and refactoring.
Seq66 has a 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 on "linux" via Meson, Qt Creator or qmake, and on Windows using MingW.
IMPORTANT: GNU Autotools is no longer supported, except in the "Autoconf" branch.
The INSTALL has been streamlined, see that file for build-from-source instructions for Linux or Windows, and using a conventional source tarball.
