Use 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/oberheim/matrix_6.electra-community-clone.fw-unknown.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 matrix_6: ask “what can the Oberheim Matrix-6 do?” and it reads this map with list_routes. See the MCP guide.
MIDI controls
1 control, each with its number, its range and the name to send
SysEx commands
| Command | Arguments | Name to send |
|---|---|---|
| Freq vcf1 | val: u7 | /matrix_6/freq_vcf1 |
Performance MIDI
Notes, pitch bend and any CC are also available: /matrix_6/note/on <note> <velocity>, /matrix_6/cc/<number> <value>, /matrix_6/pitchbend <0-16383>, /matrix_6/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 Oberheim Matrix-6?
Yes: SynthHub's hosted MCP server knows the Oberheim Matrix-6's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
