AI4AVSummary
Behringer X32 and Midas M32 are professional digital mixing consoles controllable via OSC (Open Sound Control) over UDP. All OSC communication uses port 10023. The protocol supports two modes: Immediate (request/response) and Deferred (continuous updates via /xremote registration).
Transport
protocols:
- udp
addressing:
port: 10023 # stated: "UDP port 10023 for all OSC communication"
auth:
type: none # inferred: no authentication procedure in source
Traits
- powerable # inferred: power state commands available via /config
- queryable # inferred: /info, /status, /showdump query commands present
- routable # inferred: routing commands via /ch, /bus, /mtx, /main, /outputs
- levelable # inferred: level parameter types and /meters endpoint present
