Hi Jazzsax,

You won't see your keyboard in your Mac's Preferences under Sound because it's a MIDI device, not audio.

To use the keyboard in Band-in-a-Box, click on Options, then Select MIDI Driver or Apple DLS Synth. In the window that appears, choose MacOS X CoreMIDI, and click OK.

Next, hit Options again, then CoreMIDI (Choose Ports). Select your keyboard in the MIDI In box, and Apple DLS Synth in the other boxes, then click OK.

Thanks
