When I plug my Code 50 into my macbook, my laptop recognizes that the AMP is plugged in and as an audio device but there is no input or output to/from the amp at all. Garageband also recognizes the amp but again with no input/output...
Hi Chase,
Thank yor for getting in contact, I would suggest checking the drivers on the Mac, and checking the output selectors on Garage band, as this could be causing the issue.
