Hi DarkerDepths,
the free version has no restriction with regards to audio interfaces/drivers. The differences are:
– MIDI interface setup is limited to one input and one output.
– 64-bit mixer engine option is disabled.
– Plugin multiprocessing is disabled.
– ReWire is disabled.
– Surround-sound playback is disabled.
You can also try the demo of the full version from the download section and make sure that your interface is working.
