Im running Cubase studio on my Mac. When I'm using VST instruments, there seems to be some sort of overload in the system when too many notes are played at the same time, or notes are played too quickly - sound distorts. I've searched all the problem pages but there don't seem to be any obvious answers. I'm guessing it has something to do with the running capacity of my sound card of sample rate or something. Any ideas for a quick fix?
