Can FaceTime handle 2 audio sources (microphone and instrument)?

I'm having trouble setting up my Mac Mini for an online music lesson over FaceTime. I did some testing today, and while I can clearly hear the mic and digital keyboard in my headphones, only the mic was heard at the other end of the call, with the keyboard signal being inaudible or garbled.

The mic and keyboard are connected to separate inputs of a Focusrite Scarlett Solo interface. Should I also be using audio routing software like Loopback? Would Zoom be the better alternative? Any suggestions welcome.
 
It seems like FT is a "one input" kind of thing and whatever solution used might have to be able to combine the two Focusrite channels (or any two channel device) into a single, mono signal…or at least combine them into a two-channel thing that consists of two identical monos of which FT would accept one.

The Zoom app looks like it accepts multiple inputs from a USB device but I haven't tried it:

Yeah, after I posted that I read somewhere that FT is limited in that regard. Even the aggregate audio device thing doesn't get around it.
Zoom looks like the better option here. Thanks!
 
Loopback is a third party app that allows you to reroute audio even from multichannel interfaces. It leverages Apple's Core Audio API since most professional apps and interfaces use that for the lowest latency possible anyway, e.g. I can take all inputs from my Focusrite and send mix them down to a single stream that goes to a conferencing app, or vice-versa.
