Thanks! As I mentioned, it works fine after going to series and back to parallel. Two more bugs (observations): 1) Parallel mode with Swell does not work. I use Swell with Shimmer on my Ventris in parallel. Sounds great. With the Collider, the Swell is always first and there is no way to get any immediate attack. The shimmer in parallel should always be on and there should be a note on the initial attack from that engine. Please check.... 2) You mentioned the output levels are disabled in parallel. Not on mine. They also control volume. I think 128 or so is unity?? Please advise. Thanks again for the help!
