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/steinberg/cubase.electra-community-v2.fw-12.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 cubase: ask “what can the Steinberg Cubase do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI
Notes, pitch bend and any CC are also available: /cubase/note/on <note> <velocity>, /cubase/cc/<number> <value>, /cubase/pitchbend <0-16383>, /cubase/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
Which MIDI CC controls the filter cutoff on the Steinberg Cubase?
CC 74 (0–127), named /cubase/cutoff in SynthHub's map.
How many parameters of the Steinberg Cubase can be controlled over MIDI?
SynthHub's map of the Steinberg Cubase lists 208 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 Steinberg Cubase?
Yes: SynthHub's hosted MCP server knows the Steinberg Cubase's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
