Changing the tempo of a sample in SliceX

Hi!

I'm working on a sample now that I really like but I've come across a problem. The track I've sampled is ~72.5bpm and that is a little bit too slow. I would like my track to be ~88bpm. I chop my tracks in ReCycle and then open the .rx2 files in SliceX so that I can play with it using a keyboard, I then use the piano roll to put something down.

The problem is that I have to match it with my project bpm and in SliceX the only way I can find to do that is to change the pitch to either make it go faster or slower. For this sample changing the pitch ruins the sound. Is there any way you can change the tempo in SliceX without changing the pitch?

Thanks!
