What is a sequencer?

A sequencer is a device or software program that can record, edit, and playback sequences of musical notes or sounds. It is commonly used in electronic music production to create rhythmic patterns, melodic sequences, and song arrangements.

Sequencers can vary in complexity from simple hardware units with basic functionality to sophisticated software programs with advanced features for editing and manipulating MIDI data.

Sequencers can also be used to control external hardware synthesizers, drum machines, and other MIDI-compatible instruments, allowing for precise synchronization and integration of multiple sound sources.

Some popular sequencers include Ableton Live, FL Studio, Logic Pro, and Propellerhead Reason. These programs offer a range of tools for sequencing, arranging, and mixing music in a digital environment.
