Gonna try that. Question: why does Propellerhead instruction page say use Recycle with NN-XT in Reason? I'm using DrOctoRex.yea thats why its not working, you need to slice the loop in recycle based on transients not bars. Basically a rex file will trigger at every slice point in time with the tempo in reason. So if you have one slice your loop will pretty much always be out of time. Rechop it correctly in recycle and that should fix your problem. See this http://www.propellerheads.se/products/recycle/index.cfm?fuseaction=get_article&article=howto_2
