USB midi problems op 1

My op1 isn’t sending or receiving midi and won’t sync with my Mac anymore using the USB input.
Any ideas out there about why this is happening or not happening
It’s very annoying


Have you tried a different cable ,in a different port?

would check the audio midi setup app on your mac and see if its even recognizing it at all. maybe you need to remove the device and have it create a new one?
