S2400 as interface

I have a Roland TR 8. If you use the audio through USB in Ableton, you cannot use your other audio interface at the same time.

Will the S2400 stream through the USB and not need to take the place of the interface?

the roland uses a proprietary driver so that is why it takes your card, if this uses class compliant i assume that means the other/usual asio driver is safe

Thanks! That would be helpful!
