Roland SPD-20 PRO: MIDI CC, NRPN and OSC map

The Roland SPD-20 PRO as named OSC addresses — 17 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/spd_20_pro.pencilresearch.fw-unknown.json --out-port <N> --in-port <M>

Then send OSC to 127.0.0.1:7777, for example:

osc-bridge osc-send /spd_20_pro/bank_select/msb 63

From Claude or any MCP client, the osc-bridge mcp server exposes this driver as spd_20_pro: ask “what can the Roland SPD-20 PRO do?” and it reads this map with list_routes. See the MCP guide.

Performance MIDI

Notes, pitch bend and any CC are also available: /spd_20_pro/note/on <note> <velocity>, /spd_20_pro/cc/<number> <value>, /spd_20_pro/pitchbend <0-16383>, /spd_20_pro/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.
