Hello
I know this is a place of much knowledge and interest.
I'm trying to make a 13 note base pedalboard. I have the doner pedals, I have the Arduino board, I have a reasonable amount of code suggestions, some are working (not the MIDI part) on Tinkercad. I have created a 4 X 5 matrix sketch using 113 buttons and this works.
I need to progress to getting MIDI output but this is where my knowledge started to fall down. Tinkercad doesn't have MIDI libraries nor a facility to add a Pro Micro, although I can use Leonardo as it has the same chip set.
If this makes any sense to anyone hopefully I can learn something from you. I'm loving it so far, but is now becoming frustrating.
