When I control the OB-6 via Midi with my Nord Stage 2 the Master Control Volume is changed. I think a better way would be to change the Program Volume and keep the Master Volume at the same level. This is how I know it on any keyboard I had. Furthermore when a fade out a OB-6 sound with a Expression Pedal on the Nord and I switch the Nord and the OB-6 to another programm the OB-6 is muted and I have to turn the Master Volume knob a little bit to get back to my normal level. That`s pretty anoying when playing live.
Any suggestions on that? Or might be a good task to fix with the new OS.
