Music sequencer

Device or application software that can record, edit, or play back music

A music sequencer (or audio sequencer or simply sequencer) is a device or application software that can record, edit, or play back music, by handling note and performance information in several forms, typically CV/Gate, MIDI, or Open Sound Control. Some sequencers can also handle audio and automation data for digital audio workstations (DAWs) and plug-ins.
