MIDI2 in the Real World With Zephyr
summary
Zephyr runs a working USB-MIDI2 stack that maps one USB endpoint per UMP endpoint and preserves MIDI‑1 compatibility while adding 16‑bit velocity and attribute fields; a demo sends UMP over USB and plays audio. Network MIDI2 host support and a UMP stream responder land as PR 93923 and enable DNS‑SD discovery and session auth; topology discovery works over UDP. Highlights: USB-MIDI2 merged in Zephyr 4.1, network MIDI2 host PR 93923, UMP fixed 4‑byte words, 16 groups × 16 channels = 256 channels.
