Kurzweil PC2X Keyboard won't work in Garageband
I have the MIDI out from the interface plugged into the IN port on my keyboard, and the MIDI out from the interface plugged into the OUT port on my keyboard. Audio MIDI Setup recognizes the interface, and says that it is working properly. When I Test Setup the interface, I hear little thunks when I press the keys. I can't hear any output from the computer when I play, and Garageband doesn't record anything when I try to play on the keyboard.
I've read all the help manuals, and made sure all the plugs are in the right place. Please help! I've wasted 7 hours already on this project, and can't afford not to make this work.
