I have a self built midi foot controller powered with a Teensy 3.6.
It has both Midi IN & OUT ports/circuits.
(the midi IN uses a PC900V opto-coupler)
This has worked with no issues for over 2 years now.
Yesterday, the midi appears to have stopped working.
This coincided with me unplugging & reconnecting the midi leads whilst the Teensy was powered up.
I think I have managed to narrow it down to just the midi IN not working.
Is it possibly to "fry" the midi in circuitry by disconnecting/connecting the midi lead whilst powered up?
I'm assuming it is & guessing that the most like culprit would be the opto-coupler.
Would this be correct?
