Music sequencer

In the field of electronic music, a sequencer was originally any device that recorded and played back a sequence of control information for an electronic musical instrument. Nowadays, the term almost always refers to the feature of recording software which allows the user to record, play back and edit MIDI data. This is distinct from the software features which record audio data.

Early analog music sequencers used control voltage/trigger interface, but were replaced by digital hardware- or software-based MIDI sequencers, which play back MIDI events and MIDI control information at a specified number of beats per minute.

As computer speeds increased in the 1990s, audio recording, audio editing, and sample triggering features were added to the software. Software so enhanced is called a digital audio workstation (DAW). DAWs almost always include sequencing features but, strictly speaking, go beyond what a sequencer is.

Many sequencers have features for limited music notation, or are able to show music in a piano roll notation. (For software designed specifically for music notation, see the scorewriter article.)

Though the term 'sequencer' is today used primarily for software, some hardware synthesizers and almost all music workstations include a built-in MIDI sequencer. There are also standalone hardware MIDI sequencers.

Music can also be sequenced in a using trackers such as ModPlug Tracker, and some of those are able to sequence MIDI events too.

A drum machine can be viewed as a specialized music sequencer.
