I can't remember exactly but when I 1st got it, it seemed like I could switch between any performance without the sound suddenly cutting out; Now there are only certain patches in which I can do this. Its seems pretty arbitrary. I tried looking for certain characteristics in certain patches that maybe doesn't allow it to work but Im not finding any distinguishable differences in which one patch would work but others wouldn't. Any one else having this?? I'm getting a replacement sent to me in a few days for other issues, but this was one of the main reasons I upgraded from the moxf8 to not have the sound suddenly cut off.
