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/alesis/micron.electra-thomas-moravansky-v4.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 micron: ask “what can the Alesis Micron do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI
Notes, pitch bend and any CC are also available: /micron/note/on <note> <velocity>, /micron/cc/<number> <value>, /micron/pitchbend <0-16383>, /micron/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
How many parameters of the Alesis Micron can be controlled over MIDI?
SynthHub's map of the Alesis Micron lists 207 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 Alesis Micron?
Yes: SynthHub's hosted MCP server knows the Alesis Micron's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
