  • Harmony

That translates the track 's harmony to MIDI. These can include keys, monitors, drums, or vocals to back up.

  • Drums

A very popular instrument for music makers. This allows you to import the drum line from the track easily and then, if needed, make some modifications of different beats, strokes etc.
