Emu XL-7 & MP-7 User's Group

hello, sequencer people. I have recently purchased my second MP-7. The 
first one froze up all the time, so I sold it. This second one, has 
been upgraded to 2.0, and has been reset to factory specs. My first 
four patterns were working fine, then the begining of a next pattern 
has been noticably out of time. I tried quantizing everthing to a 32nd, 
and erasing all data on the tracks not being played. I use the touch 
strip to slide my baseline only. I still have off time starts of 
patterns when I chain them together. Help. thanks, ESW.
