Routing MIDI to DLS?

Maybe a dumb question - but I’d like to route MIDI to the the built-in DLS MIDI synthesizer on OS 14.

I’m not entirely sure why it doesn’t appear as an output option in SuperCollider, but I’d be really glad if someone here knew a workaround!

I’m pretty sure macOS doesn’t directly support MIDI connections between software, only software ↔ device. But it has an IAC bus option in Audio MIDI Setup for software ↔ software.
