I completely concur with what Bachus says. Better still I prefer Midi drums over audio drums any time. Both on my Korg PA800 and even more on the old Ketron X1 I can manipulate the drums in a way you can't even get close with audio drums.
How about indvidual settings for each part of the drumset for volume, reverb, panning, on/off, etc. But if you are happy with the audio drums that's fine by me!!!

John
