hi everyone, i'm sorry to bother you with this stupid question but i read the manual and i still don't get it.

I do all my music in Reason and i wanna make some loops for Ableton Live.
I do the loops in Reason but when i import them in Live, it always sound awfull. for example, i make a loop of 4 bars of atmospheric synth but EVERYTIME i try to play the properly, it never work!!! i tried to do some time strtching and stuff but i cant make it sound natural and i feel like a moron

what are your suggestions to solve this problem???

thanx in advance
