hey, i'm a beginner using digital performer; just starting to get an idea of how to use it, though familiar with other digital recording applications. i'm looking for an effect, or something, so that i can reverse soundclips (as in, render recorded audio clips backwards). i see that the retrograde and reverse time functions apply to midi use, however, i'm trying to do this with recorded audio tracks. is this possible within the program? or must i export the samples and reverse them externally? it seems there must be a way to simply make them backwards. thanks so much, nathan.
