only letting me use 2 mics when i have 4 mics

Many multi-channel interfaces do that. It mounts as two different stereo sound devices and Audacity can only connect to one of them (at a time). I would expect the driver to have a four-channel option, though. Did you dig in the manual or other on-line info?

Audacity will cheerfully connect to multi-channel devices.

I think the Mac Composite Device can mount them, but that will also pre-mix the channels, so that’s not useful.

Even if you get it to work, there are odd considerations. Audacity only has two recording meters and Audacity will only ever play back stereo (two tracks).

One other problem. A number of systems depend on ASIO support to manage sound channels and directions. Audacity does not easily support ASIO.
