Ok,
So I built my MIDI controller that has 8 buttons and a toggle switch. Depending on what position the toggle switch is in will make it send either CC messages or Note messages.
I have noticed that if I unplug it or leave it for hours plugged in and then come back to mess with it I have to reboot Windows to get it to completely recognize.
Windows device manager says it's there, but none of the button presses are seen. Not sure why.
My code is below, is there something with my code?
