Need Help Routing Third-Party Software Audio into Zoom

Hello, I am trying to capture sound from my MPC (third-party software/hardware) and have it recorded during a Zoom meeting. I’ve tried tinkering with the audio settings on my MPC, Zoom and Macbook… but I can’t get any sound when I try recording a session.

I can hear myself just fine and random music I play on my desktop, but when I try to capture sound coming from the MPC I get no sound on the recording. I’ve tried creating aggregate devices, various multi-output device setups, and using Zoom’s native share sound functionality to no avail. I just want to use Zoom to capture music that I create and play using my MPC software/hardware, if possible, so I was hoping to see if there are solutions to help me figure this out.
