Hi Mac and Muzic Trax, thanks for your responses. I will definitely try that Muzic and yes, I understand the concerns Mac... The problem is, that the solo pianos, even at the correct tempos have funny glitches with tone and sequences... However, if you lower the tempo, even by just 10 beats, it sounds bad.. It's a shame really because, for instance, the prairie piano has only a 100 bpm tempo and it works better at higher tempos if you can't work at the 100 bpm. However, just going to 90 it doesn't sound very good. So, I figured if I could get midi file and add in the pedalling, it could work tonally better using a dedicated piano sound and the tempo would not be an issue.

But there is much in what you say Mac, I will try the experiment of Muzic and see what kind of results I get and how close to the original musical execution is there... I really wish all the solo pianos were at 65, 85, 120 and 160. That way there's enough variance to go up in bpm. Going down bpm works for some of the instruments, not for the solo piano.
