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/korg/nts_3.electra-community-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 nts_3: ask “what can the Korg NTS-3 do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI
Notes, pitch bend and any CC are also available: /nts_3/note/on <note> <velocity>, /nts_3/cc/<number> <value>, /nts_3/pitchbend <0-16383>, /nts_3/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.
Frequently asked questions
How many parameters of the Korg NTS-3 can be controlled over MIDI?
SynthHub's map of the Korg NTS-3 lists 4 MIDI CC and 48 NRPN 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 Korg NTS-3?
Yes: SynthHub's hosted MCP server knows the Korg NTS-3's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
