I have mine routed to a patch bay then patched straight into my RME Fireface.
The 8 analog inputs and patchbay combo work well for my needs but im tempted to get a mixer so i can have more running at once, without the need to render audio as often.
and of course there are the benefits of an analogue desk sound... mmm gain!!

Has anyone here used or own the Mackie Onyx? I like the look of those
