Cannot connect directly to MIDI hardware ports in SuperCollider
Pipewire 0.3.26, Arch Linux 5.12.1-arch1-1
The following SuperCollider code should initialize the MIDIClient and create a connection directly to my MIDI hardware interface and finally play a note on the first channel of that port. But it doesn't. It might be a SuperCollider issue of course but it did work before installing Pipewire, so maybe not. I can make it work by patching SuperCollider's virtual port to the hardware port in Carla, but the newByName method should connect directly according to the docs.
MIDIClient.init; m = MIDIOut.newByName("mioXL", "mioXL MIDI 1"); m.noteOn(0, 60, 64);
What could be the issue here? I'm attaching a screenshot of how it looks in sc and Carla (with the patch cord that makes it work).
