nb_plyprc

a norns classic as nb player

polyperc as you know it.

but this time limited to 6 voices to keep your precious CPU for other things and the addition of a mod section to make use of the mod-parameter of nb players. Not many scripts have it implemented (yet) but sidvagn does. The mod-depth can also be controlled via param, so perfect for midi-mapping too. If you have fx mod installed and activated you can send (and modulate) to fx of your choice.

Install and activate like all nb players.

happy percin'

Use it

Start the bridge with this driver; it forwards named OSC commands to the software:

osc-bridge run --device devices/monome/norns.vendor.fw-nb-plyprc-eb9ea92.json

Then send OSC to 127.0.0.1:7777, for example:

osc-bridge osc-send /norns_nb_plyprc/param/{id}

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

JSON

The same MIDI as norns.vendor.fw-2.9.4, which this firmware shares.

Limitations

Source: the Lua source of the norns script nb_plyprc by sonoCircuit (sonocircuit/nb_plyprc at eb9ea92), listed in norns.community. Shares the norns system OSC of monome/norns.vendor.fw-2.9.4 (port 10111, /param, /remote): give the norns' IP address as host override. Its own routes are the 16 parameter(s) whose id is written out in its source, read without running it, with range, options and default when written out too; set them while the script runs on the norns. Parameters added by libraries or engines outside the repository are not mapped either. A value goes in the parameter's units (an option's index from 1). MIDI is not mapped: the script's MIDI handling is its own and parameter MIDI mappings are learned by each user (PMAP). Untested on hardware.

Frequently asked questions

Can an AI agent like Claude control the Monome norns?

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