Roland System-1 (System-1M): MIDI CC, NRPN and OSC map

The Roland System-1 (System-1M) as named OSC addresses — 56 CC — ready to use from Claude (MCP), SuperCollider, Sonic Pi, TouchDesigner or any OSC app via osc-bridge.

Device Roland System-1 (System-1M)
Vendor Roland
OSC prefix /system_1_system_1m
Source 📦 Derived from MIDI Guide (community CC/NRPN data)

Driver file devices/roland/system_1_system_1m.json

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/system_1_system_1m.json --out-port <N> --in-port <M>

Then send OSC to 127.0.0.1:7777, for example:

osc-bridge osc-send /system_1_system_1m/general/mod 63

From Claude or any MCP client, the osc-bridge mcp server exposes this driver as system_1_system_1m: ask “what can the Roland System-1 (System-1M) do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI

Notes, pitch bend and any CC are also available: /system_1_system_1m/note/on <note> <velocity>, /system_1_system_1m/cc/<number> <value>, /system_1_system_1m/pitchbend <0-16383>, /system_1_system_1m/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.
