Hey David! Thanks for the reply!
I just checked and it's says 64, but it's probably more then that. So I guess I went over the limit of 64. I use my Alesis Nitro electric drums to trigger the drum VST, and I don't usually make parts this long. Since I play shorter drum parts for sections of my songs, so I'm guessing that's the problem.
Is there any way to get around this? Or should I just play the ending part that it cut out, and try to make it flow with the rest of the pattern?
Thanks again!
