MPC Problem With VST

Yesterday I found a dope sample. So I chopped it up and seq. it out. I like to use Reason and Korg M1 STANDALONE VST via midi interface. So I layed down a kick out of reason. It was on time perfectly ( WHEN IN RECORD MODE ) As soon as I hit the OVER DUB it jumped off a half of a beat. So I deleted it and tryed in KORG M1. Same thing happened. So I thought it was my interface. So I went to a new seq and layed down the kick in reason. After I hit the OVER DUB it was STILL on time perfectly. So I was like ok problem fixed. I added the sample. After I hit the OVER DUB, THE REASON KICK jumped off a half beat.


Can anyone help me out on this problem? Thanks TD JAY
