It might have been nice (and possibly something to think about for future styles) to have put up triggers on the acoustic set the audio drummer used, and actually HAVE a MIDI version of the same groove. Because, while I completely get your point, it is by no means the same thing as liking a groove, but wanting it played on a different sound.

ANY arranger (or at least most of them) can substitute one groove or pattern for another in the drums, guitar, bass, etc. (although they do it in MIDI), but what the Audya can't do (as you somewhat dismissively pointed out at the end) is take a groove you DO like, and play it on anything else.

This is one of the PRIMARY things that most 'tweakers' tend to do (it's certainly the easiest way to make a style fresh!).
