When you hit a key on the keyboard, you are simply sending an instruction to the software instrument, which responds by audibly producing the note you have instructed it to play.

When you record audio with a microphone, Logic stores the data as an audio file. Audio files take up a huge amount of hard disk space, and furthermore, they do not offer much room for editing.

MIDI instruments are recorded in a different way. Instead of recording the sound that is produced by the software instrument, Logic simply records the instruction that is sent to it. These recorded instructions can be manipulated after the fact, meaning you can correct mistakes or change chords, melodies and patterns at any time without having to perform the passage again. These instructions are stored as MIDI Files, which appear as MIDI Regions in the Arrange Window.


  • The steps for recording MIDI Data are the same as recording audio:
  • Arm the track using the track’s R button
  • Hit Record in the transport bar [R]
  • Play a short melody using your controller or computer keyboard with MIDI Typing turned on [CAPS LOCK]
  • Hit Stop [Space bar] to finish recording.
