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/yamaha/fs1r.electra-thor-zollinger-editor.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 fs1r: ask “what can the Yamaha FS1R do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI
Notes, pitch bend and any CC are also available: /fs1r/note/on <note> <velocity>, /fs1r/cc/<number> <value>, /fs1r/pitchbend <0-16383>, /fs1r/program_change <n>.
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.
Other versions
The Yamaha FS1R is mapped in 2 versions. per Electra preset.
Frequently asked questions
How many parameters of the Yamaha FS1R can be controlled over MIDI?
SynthHub's map of the Yamaha FS1R lists 1 MIDI CC parameters, each with its number, range and a readable name; the full chart is on this page.
Can an AI agent like Claude control the Yamaha FS1R?
Yes: SynthHub's hosted MCP server knows the Yamaha FS1R's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
