ahlstromcj / seq66
Seq66 is a MIDI sequencer and live-looper with a hardware-sampler grid-pattern interface, MIDI automation for live performance, sets and playlists for song management, scale/chord-aware piano-roll interface, song editor for creative composition, and control via mouse, keystrokes, and MIDI. Mute-groups can enable/disable multiple patterns with one keystroke or MIDI control. Supports NSM (Non Session Manager) on Linux; can also be run headless. It does not support audio samples, just MIDI.
Seq66 is a major refactoring of Sequencer64/Kepler34, both being reboots of Seq24 with modern C++ and new features. Linux users can build this application from the source code. See the INSTALL file. Windows users can get an installer package on GitHub or build it with Qt Creator. A comprehensive PDF user-manual is provided.
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.
