Hello everyone! I've had my newly bought Roland A-800 Pro Midi Keyboard Controller for over a week now and I've only played it twice so far! It's very frustrating especially since I got it to work before and now no matter what I do, there is no sound coming out! Driver is properly installed (it worked before) I set up what was needed in the "Audio Midi Setup", and in the preferences of GarageBand, it says "3 MIDI Input(s) detected" in the MIDI Status. I also have "Build-in Input/Output" selected. I first connect the Midi to the laptop, open garageband, then open the keyboard, and it then says "3 Midi Inputs detected". So what am I doing wrong!??! It's really frustrating Thank you very much for your time and help!
