The T2 play's the loop in sync with the style, however, triggering the loop from within a multi-pad is tricky since the wav file must be the same length as the recorded multi-pad. This is simply a matter of coordinating the sizes of the two which I did not have time to do as yet.

"But I still have to understand how you assign a wav file to a multipad. "

Actually, this is the easy part. Since the T2 allows you to create custom voices using WAV files, you simply go into the multipad recorder, select the Custom Voice you just made with the wav file, record your riff, and save! Works like a charm.
