Record to multiple software instrument tracks in GarageBand on Mac
You can record to multiple software instrument tracks simultaneously. In order to record to multiple audio tracks, you must have the Record Enable button 
visible on each track. The Record Enable button prepares multiple software instrument tracks to receive MIDI simultaneously.
During recording, any adjustments to knobs or other controls in the Smart Controls area are recorded as region automation. You can use automation in the Piano Roll Editor to edit the Smart Controls Recording later.
Note: Record enabling a track also lets you monitor the input.
