Need Some Serious Expert Help Please!!!

Im in need of some serious expert help. I have my drums going through seperate outputs on my MPC and through my RME ADI-8 Pro 8 channel convertors and my RME Sound Card. When ever i play a stereo sample from the mpc out output 3/4 for example and going through my convertors the sample envelopes and the sound is constantly changing from sounding more open then closed then open.Its really weird.This only happens when going through my convertors and Sound Card and only on a stereo sound. If i play the stereo sound from just the mpc and not going through my convertors and Sound Card the sample is fine and it stays normal without changing envelopes. This only happens when playing a stereo sample from my mpc through my convertors and Sound Card and a mono sample plays just fine. So im really really STUMPED on what his can be.Im using a mpc 3000.

Can anybody PLEASE help me out im really stumped and nobody i know can help me.

Thx.

uhhh phasing or whatever it's called, if you have the same drum sound panned, one on each side, it'll do that....damn, what's it called? anyway, you have to change some of the parameters of the sound, can't remember what that is exactly either.....must save brain cells....anyway, I dunno if that's what it is at all but it sounds like it

I dont have the same drum sound panned i didnt do anything to the sample at all. It only happens with a stereo sound. Please guys i really need some help on this one i cant work without solving this problem ive tried a ton of things with no luck.

Thx.

Please guys anybody? I really need a solution there has to be one.

Thx.

Hey guys thanks for trying to help. I figured out the problem. In my sound card and in cubase instead of the stereo pair panning being all the way to the left on one side and all the way too the right on the other the stereo pair was right in the middle on both sides like a mono channel should be and that was causing the phase problem.

Thx.

cool, I figured something was up with the phase steez
