One of the issues with audio drums is... it's a stereo track... you can't add reverb to it without the kick and lo toms getting muddy.

Most studios will track drums in a drum room, some nice ambiance around the drums to give them a bit of space, but then, at the board, a plate or bigger reverb will probably get added to the snare, and maybe the toms a bit to bed it in with a bigger soundfield.

But the audio drums will be fixed... can't add or subtract reverb. So, they either work with the track or they don't. In all likelihood, what is going to have to be done is dial BACK the reverb a bit on the arranger tracks so it sits a bit better with the smaller space. Whether you like that or not.

Simply one more reason why I think audio tracks are a dead end. Why can't they spend the energy and time sampling a REALLY good MIDI drumkit, with lots of velocity levels, in a nice drum room, and do away with all these problems? You still get a great drummer to PLAY the parts... but he uses a MIDI drumkit instead of the real one. Listen to any BFD or EZDrummer demos if you don't think these can sound JUST as good as a real drummer on a real drumkit!
