From memory you are using a guitar pedal stomp switch, so this could theoretically be multiple triggering and causing the overflow, but as Blindsmyth says that's a lot of button presses, so it could be that it's something else in your signal chain causing the overflow, not sure, a midi loop of some kind, your soldering....A debounce compensates for double triggering
Total newbie I must admit: how do I debounce the digital input?
Put a debouncer in line from the digital in to the midi/out/pgm trig
Using DIN midi for now which works. Tried using the usb host which worked, but the terminal said: usb host midi output ringbuffer overflow. Any idea how to fix that?
this is from your other post, what are you connecting to usb? and do you get the error now on Din midi also?
