Schmidt Synthesizer MIDI CC chart, NRPN and OSC map¶
The Schmidt Synthesizer MIDI implementation: 23 CC, 306 NRPN, each named, for Claude (MCP), SuperCollider or any OSC app.

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/schmidt/synthesizer.pencilresearch.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 synthesizer: ask “what can the Schmidt Synthesizer do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI¶
Notes, pitch bend and any CC are also available: /synthesizer/note/on <note> <velocity>, /synthesizer/cc/<number> <value>, /synthesizer/pitchbend <0-16383>, /synthesizer/program_change <n>.
Limitations¶
CC/NRPN only. SysEx (preset management, display control, bulk dump/load, vendor-proprietary opcodes) is NOT covered by pencilresearch. To extend this device with SysEx, sniff the vendor editor, add `sysex.header/footer` + `commands` blocks, and use `update_device.md` PR template.
Frequently asked questions¶
How many parameters of the Schmidt Synthesizer can be controlled over MIDI?
SynthHub's map of the Schmidt Synthesizer lists 23 MIDI CC and 306 NRPN 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 Schmidt Synthesizer?
Yes: SynthHub's hosted MCP server knows the Schmidt Synthesizer's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
