the instrument sounds on the host/slave devices?
A. Disable PROGRAM CHANGE on the MIDI controls on either the master keyboard and/or the host devices. Note that not all equipment will allow you to disable program changes. With program change, you can change the instrument setting without affecting the other equipment. This also disables program change commands coming into the MIDI IN of your critical device. Q. I need local control off, but my keyboard does not have the local control function.
