I'm using PT LE right now and I have a very stable system. The only reason I have to forget PT and go for DP or Logic is horsepower to mix... DP is dual processor ready and logic is altivec ready... ohhh, I forgot about the track count on PT LE . But I do love the stability and editing on PT. So far, I couldn't find out how to do some serious editing on DP 3 or logic... I mean... serious, FAST editing. I use those for AUDIO only, almost no MIDI at all. Can you guys comment/suggest my post?
