MIDI2 in the Real World With Zephyr
summary
Shows a concrete MIDI 2 implementation on Zephyr that sends and receives UMP packets over USB and UDP, with device tree descriptions, input callbacks and a working synth demo that plays and records. USB support is merged in Zephyr 4.1 and the Network MIDI2 host code and UMP stream responder are in a PR, making Zephyr effectively the first open source OS with network MD2 support. Demos use USB-MIDI2 endpoint per UMP group and Network MD2 over UDP with DNS-SD discovery and they successfully discover topology and exchange high‑resolution 16‑bit velocity and Q7.9 pitch attributes.
