It is a bit unclear how you have things assigned and routed for the above.
If you have your drums inserted in the synth rack, you should have either a simple instrument track or (and this is MY preference) a separate midi track to trigger the drum synth and one or more (I use 32) audio tracks present in a track folder so that each drum kit piece is routed to its own audio track. IF this is how you have things set up, then you would be recording the MIDI track, not the audio track(s) for the drums. You could then bounce the midi to audio afterward, if you wanted to.
If you have something else in mind, please detail this so that I can better understand what you seek to do, and can better assist you.
Thanks,
