To select a drum map for a MIDI track, open the Drum Maps pop-up menu in the Routing section of the Inspector or the Map pop-up menu in the Drum Editor, and select a drum map.
To deactivate the drum map functionality in the Drum Editor, open the Drum Maps pop-up menu in the Routing section of the Inspector or the Map pop-up menu in the Drum Editor, and select No Drum Map.
Even if you do not use a drum map, you can still separate sounds by name via a name list.
Note
Initially, the Drum Maps pop-up menu only contains GM Map.
