Hi there
I have quite a specific problem with my Sub 37:
Whenever I change the presets via my MIDI controller (i.e. a Roland AX-7) the presets on my Sub 37 get changed excactly how they should. BUT nearly every Program Change also activates the Sub's Duo Mode. First I thought the AX-7 sends the Duo-Mode-activation as an «invisible» Control Change (CC110 as the manual says) but … it doesn't. I checked that with a MIDI monitoring tool.
Do you guys have any idea what's going on there?
Thank you for your help!
