anyway, having done this now with some of the piano tracks, just wanted to mention that it does work, but it works better with some piano tracks than others... Definitely if you have a piano track that's not sounding good because of speed it's worth at try... I'm next going to try to find out if some that aren't working as good it's because I'm rendering them at the incorrect tempo for optimum results... Like for instance, if the tracks work best at 85 bpm and I'm rendering them at 65 bpm, that may be causing the problem... The other problem is just editing the pedaling... But I knew that going into this...
