This driver comes from documentation or community data and has not been checked on real hardware. If you own one, a quick test and a pull request promoting it helps everyone — see CONTRIBUTING.
How do you control 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/yamaha/revision_49_of_yamaha_dx_7_ii.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 revision_49_of_yamaha_dx_7_ii: ask “what can the Yamaha Revision #49 of Yamaha DX-7 II do?” and it reads this map with list_routes. See the MCP guide.
