Electra Community Polyexciter (13) MIDI CC chart, NRPN and OSC map¶
The Electra Community Polyexciter (13) MIDI implementation: 66 CC, each named, for Claude (MCP), SuperCollider or any OSC app.
| Device | Electra Community Polyexciter (13) |
|---|---|
| Vendor | Electra Community |
| OSC prefix | /polyexciter_13 |
| Source | 🎛️ Derived from an Electra One community preset |

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/electra-community/polyexciter_13.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 polyexciter_13: ask “what can the Electra Community Polyexciter (13) do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI¶
Notes, pitch bend and any CC are also available: /polyexciter_13/note/on <note> <velocity>, /polyexciter_13/cc/<number> <value>, /polyexciter_13/pitchbend <0-16383>, /polyexciter_13/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 Electra Community Polyexciter (13) can be controlled over MIDI?
SynthHub's map of the Electra Community Polyexciter (13) lists 66 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 Electra Community Polyexciter (13)?
Yes: SynthHub's hosted MCP server knows the Electra Community Polyexciter (13)'s MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
