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/roland/juno_106.electra-mravitz-2-32.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 juno_106: ask “what can the Roland Juno-106 do?” and it reads this map with list_routes. See the MCP guide.

Limitations
Imported from an Electra One community preset. The mapping reflects the preset author's editorial choices: parameter naming, ranges, and which params are exposed. Untested on hardware in this repo.

Frequently asked questions
Can an AI agent like Claude control the Roland Juno-106?
Yes: SynthHub's hosted MCP server knows the Roland Juno-106's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
