Audya's real drums are exceptional... but as you mention ease of editing as being a primary requirement (I have the same priorities!), I wouldn't go that route.

The audio loops are GREAT, but you can't really do much to them. Forget editing the kick to a slightly different beat, forget about changing the backbeat, forget about substituting a different snare sound, or all the other myriad things that doing it in MIDI allow you.

You gain, but you also lose...
