Elektron Analog Four: MIDI CC, NRPN and OSC map¶
The Elektron Analog Four as named OSC addresses — 5 CC, 45 NRPN — ready to use from Claude (MCP), SuperCollider, Sonic Pi, TouchDesigner or any OSC app via osc-bridge.

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.
Other variants of this device: analog_four.pencilresearch.fw-unknown.
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/elektron/analog_four.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 analog_four: ask “what can the Elektron Analog Four do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI¶
Notes, pitch bend and any CC are also available: /analog_four/note/on <note> <velocity>, /analog_four/cc/<number> <value>, /analog_four/pitchbend <0-16383>, /analog_four/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.
