Hi all, I'm a beginner and was wondering, if someone could give me a head start on a project of mine. Imagine the following: As a source material I have 20 bars of music. As a target I have a structure of 200 empty bars with changing time signatures. Now I'd like to fill the 200 bars with snippets from the source material, i.e. copy from the source to the target, bar by bar in a specified (nonrandom) pattern, starting at each bar of the source material from the beginning, for the duration of the target bar (which is changing because of the changing time signatures). I hope my description makes sense. Any help is greatly appreciated. Thank you! Laure
