MUSIC SEQUENCER

In the field of electronic music, a 'sequencer' was traditionally a device or piece of software that allows the user to record, play back and edit musical patterns. This usually did not include the ability to record audio, only the control information for synthesizers to recreate the composition. As most sequencers now feature audio editing and processing capabilities, the line has been blurred with digital audio workstations such that the terms are often used interchangeably. Though the term 'sequencer' is today used primarily for software, some hardware synthesizers and almost all music workstations include a built-in MIDI sequencer, while drum machines generally have a step sequencer built in. There are still also standalone hardware MIDI sequencers, though the market demand for those has diminished greatly in the last ten years.
Many sequencers have features for limited music notation, and most are able to show music in a piano roll notation. (For software designed specifically for music notation, see scorewriter.)
Music can also be sequenced using trackers such as ModPlug Tracker, and some of those are able to sequence MIDI events too.

History

Early analog music sequencers used a 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) to distinguish from sequencers and multitrack recording programs. DAWs almost always include sequencing features but, strictly speaking, go beyond what a sequencer is.

Step sequencers

A special case of sequencers are step sequencers. Instead of recording played notes or drawing notes by hand on the piano roll, the user composes patterns using a grid of (usually) 16 buttons, or steps, each step being 1/16th of a measure. Step sequencer patterns are monophonic by nature, but usually a single pattern may contain individual subpatterns for a number of different instruments. These patterns are then chained together to form longer compositions. Step sequencers are mostly used in drum machines and grooveboxes.
