i loaded up a sample on reason and placed the drums and i looped a bar over and over and placed the drums and everything was great but wen i switched the loop after a few bars, the drums just started slowing down and took the whole thing off course. no matter wut other loop i use, it wont work and i dont know wut the problem is. all the loops are the same tempo and match up perfect so can sum1 help me out.

what do you mean when you say that 'you switched the loop'?
What device are you using to play the loop?

when i say i switch the loop, i mean the part where the beat changes if u get wut im saying, to play the samples im using an nnxt and a redrum for drums

load the beat up on here and I will take a look at it.

heres the beat, its a real rough version but the point of it messing up is like 1:05 http://www.zshare.net/audio/9846662c6d65d0/

here it is, its a real rough version but the point where it all goes downhill is at 1:05 http://www.zshare.net/audio/9846662c6d65d0/

I was talking about the actually reason file. Upload that so I can actually take a look at what happened in the file.

Well, when I went and listened to it....

first impression was that it seemed like the sample that came in right when it started messing up was faster than the beat that you already had going.

Yeah you can change that if you cut it cleanly and then slice it in recycle. which you can get on mac now.
