problems with sequence files linking "musically" are usually corrected by shaving time off the end of seq 1 or the begining of seq 2 - sometimes quantizing the first beat of seq 2 has worked - sometimes there's a little silence recorded at the end of seq 1
that needs to be erased - it depends on the music and your tenacity to solve the problem - I've done many large projects with the mr-76 as the center of my studio and it took time to get used to the quirks - It's well worth the effort.
