That's a trip. If I still had my Mpc I'd be better equipped to help you get to the bottom of the problem. I was reading through another thread here on the forums and stumbled upon this:

I recorded a 4bar loop from my mpc directly into Record without being synced and it looped perfectly in Record. The sound quality is better then Reason's. I also found that I could manipulate my audio easier than I could in Ableton, that's just me though.
I'm sure it wont replace Logic or Protools but if you're just into recording beats or instrumentals it's worth checking out.
I'm pretty sure what this guy did was just record the audio straight into Record without sync and resize the clips so that they loop perfectly....I know a lot of the cats on these forums use Pro Tools in the same way to build their tracks and don't even bother with syncing and some do midi sync...I guess it comes down to what works best for each person. Either way man it sucks you're having this issue and I hope you get it worked out by Pro Tools or whatever it may take. Sorry I couldn't be of more help.
