My Midi Device Has Both USB and Midi Connecters Which do I Use to Connect to my Mac Pc?
1) The preferred and easiest choice is the USB since all pc have these ports and no pcs have midi ports which also require a USB to midi adapter. This will enable you to communicate with midi commands. If the device has USB audio implementation, you can also use the USB ports for audio recording.
2) On the device, go into the midi utility menus and select USB as the port to be used. This will activate communication thru that port.
