 A driver is required for  USB audio . It can be found at:

USB IN

CH 1 Backing Track L

CH 2 Backing Track R

CH 3 Dry vocal in

CH 4 NaturalPlay IN

If no signal is transmitted to the product on USB audio channel 3, the product will use analogue in for the voice input.

So, you could use channels 1&2 to input stereo tracks from your DAW but sing into the product via your mic.

Note that the input of channels 1 & 2  is NOT passed to the USB outputs, but IS passed to the Main analogue outs.

If you use a computer for backing tracks, they will get sent analogue to the PA. Volume control for those tracks happens at the computer.

NaturalPlay IN is not connected to the audio output. It is used only for NaturalPlay chord input. This is intended to allow you to use a “guide track” for NatualPlay that you may not want heard in the mix.

It could be dry guitar chords or piano chords, with different voicings or placement in order to create your desired harmony output.
