So... as mentioned above, I have a Digitech Control 7 foot pedal... which has it's OWN problems...
But the one I'm currently interested in is that I have it connected with a USB/Midi cable (which I know to be working because I've tested it with other midi devices). It appears to be sending a signal because a little green light goes on when I step on it (the light is on the converter cable... yet no signal is received by the computer.
I'm on a mac and using Audio Midi Setup. If I connect any other midi device at all it works just fine.
If the little light wasn't flashing when I stepped on it then I would just yank the board and replace it with an arduino or raspberry pi or something.
Any idea why this might be happening?
