Roland Jupiter-X (Jupiter-Xm): MIDI CC, NRPN and OSC map¶
The Roland Jupiter-X (Jupiter-Xm) as named OSC addresses — 22 CC — 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.
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/jupiter_x_jupiter_xm.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 jupiter_x_jupiter_xm: ask “what can the Roland Jupiter-X (Jupiter-Xm) do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI¶
Notes, pitch bend and any CC are also available: /jupiter_x_jupiter_xm/note/on <note> <velocity>, /jupiter_x_jupiter_xm/cc/<number> <value>, /jupiter_x_jupiter_xm/pitchbend <0-16383>, /jupiter_x_jupiter_xm/program_change <n>.
Limitations¶
CC/NRPN only. SysEx (preset management, display control, bulk dump/load, vendor-proprietary opcodes) is NOT covered by pencilresearch. To extend this device with SysEx, sniff the vendor editor, add `sysex.header/footer` + `commands` blocks, and use `update_device.md` PR template.
