Hello, I've owned a Yamaha Moxf8 for about 4 years now. I've gone back and forth from using an amplifier and using GarageBand on Mac. I recently sold my Mac Mini. However, I cannot seem to remember the settings to get the keyboard to change the output back to the L/mono 1/4" jack. I would have trouble getting the MIDI output working, but now it's the other way around. I'm not sure what I'm doing wrong, so if you could give me the settings I would need to change and what to, that would be most helpful.
