Seq66 is a MIDI sequencer and live-looper with a hardware-sampler-like grid-pattern interface. It’s built around the concepts of loops.
Seq66 is a reboot of Seq24, a live-looping sequencer with an interface similar to a hardware sequencer,
refactored for newer versions of C++ for faster and simpler code. It drops the Gtkmm user-interface for Qt 5, and has better handling of sets, mute-groups, sessions, playlists, and automation control.
It supports the Non/New Session Manager, has a metronome function, multiple input port recording, a modi able color and brush palette, and Qt style-sheets.
This is free and open source software.
Other features include:
- Supports MIDI only (the software does not handle audio, nor is it a synthesizer).
- Live tab – provides a grid of patterns that display recorded MIDI data, status information, and provides popup-menus for each pattern.
- Song Editor – combines all patterns into a complete tune with controlled repetitions of each pattern.
- Pattern Editor – record and edit notes and other MIDI events.
- Event Editor – observe the details of events. It’s useful for trouble-shooting a song.
- Playlist Editor – create playlists.
- Sets Editor – see, edit, and rearrange the sets that a tune contains.
- Mutes Editor – turn on or off multiple patterns at once.
- Session tab – displays certain aspects of the running setup.
- MIDI control/display automation
- Supports ALSA and JACK (but not Pipewire).
