Hi Shastastan,

Since the SD-2 is the audio device that you're trying to record, you'd have to hook the output of the SD-2 to the input of your UA-4X. Ensure Audacity/RealBand is set to record the input from your UA-4X. Then simply hit Record, and press play in Band in a Box.

If you open the Band in a Box song in RealBand, you can do all of this in one program as Mac was suggesting.

HTH,
Will
