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.
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/roland/jx_3p_organix_mod.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 jx_3p_organix_mod: ask “what can the Roland JX-3P (Organix Mod) do?” and it reads this map with list_routes. See the MCP guide.

Frequently asked questions¶
Which MIDI CC controls the filter cutoff on the Roland JX-3P (Organix Mod)?
CC 19 (0–127), named /jx_3p_organix_mod/1_cutoff in SynthHub's map.
How many parameters of the Roland JX-3P (Organix Mod) can be controlled over MIDI?
SynthHub's map of the Roland JX-3P (Organix Mod) lists 32 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 Roland JX-3P (Organix Mod)?
Yes: SynthHub's hosted MCP server knows the Roland JX-3P (Organix Mod)'s MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
