Sonic Potions LXR MIDI CC chart, NRPN and OSC map

The Sonic Potions LXR MIDI implementation: 289 CC, each named, for Claude (MCP), SuperCollider or any OSC app.

Maker: Sonic Potions
Version: per Electra preset
Source: Electra One preset
OSC prefix: /lxr

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/sonic-potions/lxr.electra-bjorn-bischof-bc0-37.fw-unknown.json --out-port <N> --in-port <M>

Then send OSC to 127.0.0.1:7777, for example:

osc-bridge osc-send /lxr/kick_wave 63

From Claude or any MCP client, the osc-bridge mcp server exposes this driver as lxr: ask “what can the Sonic Potions LXR do?” and it reads this map with list_routes. See the MCP guide.

Frequently asked questions

How many parameters of the Sonic Potions LXR can be controlled over MIDI?

SynthHub's map of the Sonic Potions LXR lists 289 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 Sonic Potions LXR?

Yes: SynthHub's hosted MCP server knows the Sonic Potions LXR's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
