Hello,
I just got an old Johannus organ (1410) in excellent condition for a small amount of money. It has two manuals and pedal. The manuals are fixed to midi channel 1 and 2 and the pedal is fixed to channel 3. That means you cannot change these midi channels. Period.
My problem: I like to use a third manual which I own since years. But this one also uses channel 1 by default. You can change the channel only temporarily to i.e.7. But whenever you turn power off and on it switches back to channel 1. Problem: The keys to switch the channel are not so easily accessible, because I like to integrate this manual into the corpus of the organ and these keys are now inside of the organ.
What to do? Any Ideas? I hoped that there would be a little, cheap piece of hardware available which would just change the midi channel. But I didn't find anything. By googleing (??
) the whole day I found only that there are some people with the same problem - but no solution.
Thank you for any help and best regards
