Hello! Thanks for this. It's definitely doing something! I sent CC00 and CC32 to correspond to MSB=127 and LSB=0 and then a patch change that matches the PGM# in the Drum Voice list. This worked when I selected the option in Cakewalk to send the program change using CC32. I tried this on several different channels and was able to select different kits. So, I thought I'd create a template to do this on all channels to initialize the QY with a different kit on each channel. The first four channels worked perfectly and were set to "standard" "standard2", "dry" and "bright", but channels five to sixteen were all set to DS2. I saved my Cakewalk file and restarted Cakewalk and reopened it. The controller 0 and 32 events have disappeared and the patch change messages have been changed from controller 32 to normal and a big bank number calculated. When I play the sequence everything is set to DS2. I think I will manually set the kits how I want them on a bunch of songs and send my sequence to that song to get the mappings I want. I'm spending too much time trying to get the the PC to talk to the QY and not making any music! Thanks again for your help. Best Giles ?
