Hi, I have a Yamaha P45 and Garageband in my Mac. My Yamaha keyboard has a USB Type B output (USB to host). My Mac, has a USB C entry. I never used garage band but when you have to choose a track type, it recommends a MIDI type for a keyboard. In this case, not sure if my Yamaha P45 has MIDI exit in that USB Type B output and if I need to buy any intermediate interface to convert from audio to Midi. Anyone out there who can enlighten me?
