Recording with Audio Interface

Hi, I have two questions about recording. 1) How do I connect the dato duo to an audio interface (Behringer UMC204HD)? 2) I’m trying to record dato duo with garageband. The USB-C option let me record the pitch and length of the notes, but it doesn’t record the sound effects (e.g. wave, freq, glide etc) even though the garageband visually shows some dramatic lines when I play with the sound effects (maybe frequency changes?). How do I play the sound effects from the garageband? Thank you. Z
