Seems I was able to do the feature of “playing” the BBD chips via MIDI before, but now I can’t seem to get audio off the chip without having audio fed into the 108M.
Is this function enabled with MIDI CC#77?
Looks like CC77 turns it on and off, and the default is on at power on.
I usually have to crank the feedback and put a bit of audio in to get the feedback self oscillating. Even a click or blip works. Sometimes flipping the flange chorus switch gets it going.
The notes are limited as well, the low lows and high highs don’t sound. It’s not the most useable sound without a VCA of some sort with it, so you can keep the feedback going.
