MIDI IN not working [SOLVED!]


Hi all,

My MIDI IN port isn’t working. The activity LED lights up, but Jack doesn’t see any MIDI events from it. USB MIDI works fine, as does the MIDI OUT port, wired in the same way. Any help here?


IT LIVES! It ended up being a poorly seated optocoupler on the MIDI IN port. I use sockets when I solder chips, guess I didn’t seat it right.
