I have a power mac G4. my loops once had several instruments playing a tune,. Some went south, now all the instruments separated out and into separate single notes. A single pluck of a string, a single toot of a horn. The FX seem to all be there. The drums don't jam on and on. each loop is a single drop of a drum stick and that's it. Just "Bonk!" instead of bonk bonk ratta datta crash."
