Garageband not seeing Midi inputs
I have Garageband 10.2. I have an older Roland D-50 keyboard using midi to usb. When I connect it to the MacPro, a message comes up saying a new midi input is recognized. When I go to Audio Midi Controller, the D-50 is recognized. But there seems to be no opportunity to select the midi as the input to record. When i press keys on the keyboard there is no sound detected or recorded on the track. Am I missing something or is there a problem with High Sierra? TIA,
Jeff
