Knowra Music sequencer Music sequencer A device or software application that records, edits, and plays back musical performances or instructions in a timed sequence. It can control electronic instruments or arrange recorded audio.
MIDI : A digital standard for exchanging performance messages between electronic instruments, computers, and controllers. MIDI carries note and control events that many sequencers record, edit, and transmit.
Musical time : The organization of musical events into durations, beats, and larger rhythmic units. A sequencer’s timeline represents musical events through measured durations and positions.
Drum machine : An electronic instrument designed to create and play rhythmic patterns using synthesized or sampled drum sounds. Drum machines use sequencing to program and repeat percussion patterns.
Music box : A mechanical instrument that plays tunes using pins or teeth to trigger tuned parts as a cylinder or disc turns. Music boxes demonstrate early mechanical storage of a fixed musical sequence.
Tracker music : Music composed in tracker software by arranging note and effect commands in rows and channels. Trackers present sequences as command tables rather than the piano-roll view common in other sequencers.
Piano roll : A graphical editor that displays musical notes as blocks positioned by pitch and time. Its grid is a common way to place and edit sequenced notes.
Tempo : The speed of music, commonly measured in beats per minute. Tempo determines how quickly a sequencer’s beats and patterns unfold.
Music production : The process of creating, recording, editing, and finishing music. Sequencing is a central workflow in much computer-based music production.
Player piano : A piano that plays automatically from instructions encoded on a perforated paper roll. Its rolls stored timed performance instructions that could be replayed mechanically.
Notation software : Software for creating, editing, and printing musical scores in standard notation. Notation software centers written scores, while sequencers center timed playback and performance data.
