DSI Prophet 12 MIDI CC chart, NRPN and OSC map¶
The DSI Prophet 12 MIDI implementation: 246 NRPN, each named, for Claude (MCP), SuperCollider or any OSC app.
| Device | DSI Prophet 12 |
|---|---|
| Vendor | DSI |
| OSC prefix | /prophet_12 |
| Source | 🎛️ Derived from an Electra One community preset |
| Revision | per Electra preset |
| Upstream | electra-preset |
| Driver file | devices/dsi/prophet_12.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.
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/dsi/prophet_12.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 prophet_12: ask “what can the DSI Prophet 12 do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI¶
Notes, pitch bend and any CC are also available: /prophet_12/note/on <note> <velocity>, /prophet_12/cc/<number> <value>, /prophet_12/pitchbend <0-16383>, /prophet_12/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.
