Distributed under the terms of the GPL-2.0-or-later license,[3] Seq24 is free software.[4]

Seq24 is intended to be similar to hardware sequencers/samplers such as Akai's MPC line of instruments. It works by sequencing smaller sequences or loops of MIDI notes and performance information into larger music sequences in a manner similar to the way in which Sony's Acid software is used to sequence audio clips. In order to do this, it has a patterns panel, a pattern editor and a song editor.[1] Sequences are saved as Standard MIDI file format, type 1.[5]

While developed from 2002 to 2006 by Rob Buse, a team (calling themselves simply 'Seq24team') picked up the project in 2008 with Rob's blessing, and resumed work with release 0.8.8.

Forks

edit

Several follow-up forks and reworks of the original tool exist, listed below:

  • seq42, oriented on song editing, rather than live performance. Original version is no longer maintained.
  • sequencer64, seq24 heart with 6 years of extensions.
  • seq66, a major refactoring with pattern banks, playlists, piano roll, song layout, MIDI control/status for live performance etc., Qt based.
  • seq192, "with less features but more swag".
