Roland S-1: MIDI CC, NRPN and OSC map¶
The Roland S-1 as named OSC addresses — 54 CC — ready to use from Claude (MCP), SuperCollider, Sonic Pi, TouchDesigner or any OSC app via osc-bridge.
| Device | Roland S-1 |
|---|---|
| Vendor | Roland |
| OSC prefix | /s_1 |
| Source | 🎛️ Derived from an Electra One community preset |
| Revision | per Electra preset |

| Driver file | devices/roland/s_1.json |
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.
Other variants of this device: s_1.pencilresearch.fw-unknown.
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/roland/s_1.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 s_1: ask “what can the Roland S-1 do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI¶
Notes, pitch bend and any CC are also available: /s_1/note/on <note> <velocity>, /s_1/cc/<number> <value>, /s_1/pitchbend <0-16383>, /s_1/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.
