I posted earlier a problem with my keypad library, while I solved that I instantly ran onto another problem. I have a Arduino Micro (original). I am sending midi thru USB using my numpad keypad matrix and im using the keypad library. What doesn't work is that when I press one of the keypad buttons the other ones stop functioning. This makes my device useless unless im running the drum sequencer. Can someone point me in the direction where this could fail? Is it the MIDIUSB that interrupts the loop or something similar? I am fairly new to arduino and coding.
Thank you
