KORG 01R/W: MIDI CC, NRPN and OSC map¶
The KORG 01R/W as named OSC addresses — 14 CC, 74 SysEx commands — ready to use from Claude (MCP), SuperCollider, Sonic Pi, TouchDesigner or any OSC app via osc-bridge.
| Device | KORG 01R/W |

| Vendor | KORG |
| OSC prefix | /01r_w |

Not tested on the device yet
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/korg/01r_w.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 01r_w: ask “what can the KORG 01R/W do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI¶
Notes, pitch bend and any CC are also available: /01r_w/note/on <note> <velocity>, /01r_w/cc/<number> <value>, /01r_w/pitchbend <0-16383>, /01r_w/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.
