README.mdfrom the author's repository; not claimed yet, anyone can improve itEdit

From the README of sarweiler/zellen at 355e576.

Zellen is currently not in active development, since I do not own a Norns anymore. If anyone wants to take over, feel free to fork the repository and create a new thread for it in the lines library. If you do so, send me a message on lines and I will happily link your new repository here and in the old lines thread.

zellen

A sequencer for Monome norns based on Conway's Game of Life.

Usage

Grid: enter/modify cell pattern
KEY2: play/pause current generation (semi-manual mode), advance sequence (manual mode), play/pause sequence (automatic mode)
KEY3: advance generation
hold KEY1 and press KEY3: erase the board
ENC1: set speed (bpm)
ENC2: set play mode (see below)
ENC3: set play direction (see below)
hold KEY3 + ENC3: time jog

Play Modes

Set the play mode with ENC2. * reborn (default): Play a note for every cell that was born or reborn (= has exactly three neighbors), regardless of the previous state of the cell * born: Play a note for every cell that was born (has exactly three neighbors and was not alive in the previous generation) * ghost: Play a note for every cell that is dying(has less than two or more than three neighbors). Ghost notes can have a different pitch! (See the "ghost offset" setting in the parameters screen.)

Play Direction

Set the play direction with ENC3. * up: Cells on grid are played from top left (lowest note) to bottom right (highest note). * down: Cells on grid are played from bottom right (highest note) to top left (lowest note). * random: Cells are played in random order. The randomized order will be stable for a generation and will be re-randomized for every new generation. * drunken up: Like up, but decides for each step randomly if it goes up or down. * drunken down: Like down, but decides for each step randomly if it goes up or down.

Sequencing modes

Set the sequencing mode in the parameters screen. Default is semi-automatic. * manual: Press KEY2 to play the next step in the sequence for a single generation. * semi-automatic: Plays the sequence for a single generation (and loops it if "loop seq in semi-auto mode" is enabled (default)). * automatic: Like semi-automatic, but automatically calculates the next generation and plays it.

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-zellen-355e576.json

Then send OSC to 127.0.0.1:7777, for example:

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

From Claude or any MCP client, the osc-bridge mcp server exposes this driver as norns_zellen: 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 zellen by sbaio (sarweiler/zellen at 355e576), 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 33 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.
