Roland GI-10 MIDI CC chart, NRPN and OSC map

The Roland GI-10 MIDI implementation: 15 SysEx commands, each named, for Claude (MCP), SuperCollider or any OSC app.

Device Roland GI-10
Vendor Roland
OSC prefix /gi_10
Source πŸŽ›οΈ Derived from an Electra One community preset
Revision per Electra preset
Upstream electra-preset
Driver file devices/roland/gi_10.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 β€” 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/roland/gi_10.json --out-port <N> --in-port <M>

Then send OSC to 127.0.0.1:7777, for example:

osc-bridge osc-send /gi_10/midi_channel

From Claude or any MCP client, the osc-bridge mcp server exposes this driver as gi_10: ask β€œwhat can the Roland GI-10 do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI

Notes, pitch bend and any CC are also available: /gi_10/note/on <note> <velocity>, /gi_10/cc/<number> <value>, /gi_10/pitchbend <0-16383>, /gi_10/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

Can an AI agent like Claude control the Roland GI-10?

Yes: SynthHub's hosted MCP server knows the Roland GI-10's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
