Waldorf microQ Arp MIDI CC chart, NRPN and OSC map¶
The Waldorf microQ Arp MIDI implementation: 31 SysEx commands, each named, for Claude (MCP), SuperCollider or any OSC app.
| Device | Waldorf microQ Arp |
|---|---|
| Vendor | Waldorf |
| OSC prefix | /microq_arp |
| Source | 🎛️ Derived from an Electra One community preset |
| Revision | per Electra preset |
| Upstream | electra-preset |
| Driver file | devices/waldorf/microq_arp.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/waldorf/microq_arp.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 microq_arp: ask “what can the Waldorf microQ Arp do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI¶
Notes, pitch bend and any CC are also available: /microq_arp/note/on <note> <velocity>, /microq_arp/cc/<number> <value>, /microq_arp/pitchbend <0-16383>, /microq_arp/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 Waldorf microQ Arp?
Yes: SynthHub's hosted MCP server knows the Waldorf microQ Arp's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
