Pitfalls

item: There are pitfalls in using equal division within which

to calculate 2-interval-patterns which the unwary traveler

will most certainly fall into.

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-pitfalls-c5e4074.json

Then send OSC to 127.0.0.1:7777, for example:

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

From Claude or any MCP client, the osc-bridge mcp server exposes this driver as norns_pitfalls: 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 pitfalls by delineator (robmckinnon/pitfalls at c5e4074), 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 18 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. 2 parameter call(s) could not be read without running the script (ids built at run time, values from variables) and are not mapped: reach them with the base driver's /param/{id}. 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.
