Use it
Find the MIDI ports, then start the bridge with this driver:
osc-bridge detect # prints the ready-to-run line for what is plugged in
osc-bridge run --device devices/ableton/mixer.electra-larry-van-doorn-v6.fw-unknown.json --out-port <N> --in-port <M>
Then send OSC to 127.0.0.1:7777, for example:
From Claude or any MCP client, the osc-bridge mcp server exposes this driver as mixer: ask “what can the Ableton Mixer do?” and it reads this map with list_routes. See the MCP guide.
