I've changed my mind again. Under the advice of PRSplaya I've started making use of Acid pro 4 because it's relatively straight forward and doesn't deal primarily with midi. I've gone and discovered some short .wav files of drums beats, fills and such. I understand the concept of looping but what in the sam hell do I use to loop them? And - are they confined to the tempo they were recorded in? That'd really blow, to find the exactly loop to fit the tune and then have it in the wrong tempo. I'm right clueless in this department.

... Is there something in Acid that'll piece those .wav files together and (after some help file reading) stretch them to the correct tempo or do I have to make use of an exterior program?
