make composing, recording, and mixing music

Is it possible to use the Cubebase elements 12 demo program or something similar with Quad Cortex, or is a separate usb-interface box also required?

I never got anything to come through from the program to the handset.

The QC is a core audio compliant interface and works with any DAW/recording application where inputs/outputs can be specified.

Thanks, how i specified QC?

I apologize. I don’t understand your question.
