you dont want the overhead of decoding multiple mp3 streams in realtime (by default, live reads the wav in realtime each time it plays, a lot like a record player... )applying pitch or time shifting, and then output as an uncompressed stream. you can upgrade hard drives with much more ease than a CPU, and ableton can read from CD or dvd, which helps (cd or dvd of .wav)
-Joe i discovered ableton live a few days ago and have started to chop my vinyls into handy loops. it's really sick work but on the other hand i can't wait to add this to my vinyl/fs set. as far as i got it, most of you use ableton to play entire tracks with it? uhm, i can't open any mp3's here, you guys have got too much hd space for all the .wavs or ??? am i too dumb? cheers, ronny
