sequencer

SEE-kwuhn-ser /ˈsiːkwənsər/
nounB2
technical

A hardware device or software application that records, edits, and plays back musical data (typically MIDI) in a programmed chronological order.

A sequencer does not record actual audio waves; instead, it records instructions (like which note to play, when, and how loud) and sends them to a synthesizer or sampler.

The story behind the word. The word comes from the Latin 'sequi,' meaning 'to follow.' Early industrial sequencers were used to control automated factory machinery; in the mid-20th century, musicians adapted this concept to trigger musical notes in a strict, automated order.
