Note that processing in SONAR on any of these tracks will not affect how the AD2 Master (ST) track will sound only processing within Addictive Drums 2 will affect the way this track sounds. For convenience, the Overhead, Room, and Bus tracks are all formatted as stereo as well (as indicated by (ST) on the respective tracks. Most of the subsequent tracks are mono outputs for each individual drum from Addictive Drums 2, allowing you to process the audio from each drum kit piece individually. The first track is a Master Track, which outputs all the sound from Addictive Drums 2 onto one stereo track. You can also insert any beat directly from Addictive Drums 2 onto track 15 by clicking the “Beats” tab in the upper-right corner of Addictive Drums 2, highlighting any beat and dragging it to Track 15. Track 15 is your MIDI track, which you can use to input the MIDI data for Addictive Drums 2.
