MIDI sequencer

A MIDI sequencer is a software or device used to record, edit, and play back musical notes and control signals. It allows musicians to arrange and synchronize different instruments or sounds by sequencing MIDI data—digital messages that specify note pitches, timing, duration, and other parameters. Think of it as a sophisticated digital sheet music creator that doesn’t store actual sounds but directs electronic instruments or virtual instruments to produce music precisely and consistently. This makes it a powerful tool for composing, editing, and performing music across various hardware and software platforms.
