/midibox_sid
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/ucapps-de/midibox_sid.pencilresearch.fw-2.0.json --out-port <N> --in-port <M>
Then send OSC to 127.0.0.1:7777, for example:
osc-bridge osc-send /midibox_sid/lead_engine_arp/voice_1_2_3_arp_speed 31
From Claude or any MCP client, the osc-bridge mcp server exposes this driver as midibox_sid: ask “what can the uCApps.de MIDIbox SID do?” and it reads this map with list_routes. See the MCP guide.

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
Which MIDI CC controls the filter cutoff on the uCApps.de MIDIbox SID?
CC 4 (0–127), named /midibox_sid/lead_engine_filter/filter_cutoff_frequency in SynthHub's map.
How many parameters of the uCApps.de MIDIbox SID can be controlled over MIDI?
SynthHub's map of the uCApps.de MIDIbox SID lists 225 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 uCApps.de MIDIbox SID?
Yes: SynthHub's hosted MCP server knows the uCApps.de MIDIbox SID's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
