pit orchisstra

the game of snake
a group of snakes is a pit
live loooong and prosper

Click the image above for a tutorial. For more discussion, see the thread on lines.

This is a sequencer script inspired by the game of snake. Each snake can turn left or right and only steps one square forward. Poke the grid or press K2 to use Food View to place food onto the grid. If the snake eats a food, a note will be played depending on the location on the grid the food was in and the length of the snake will increase. If a snake runs into itself or any other snake, the snake will die and respawn at the minimum length. However, each of these rules can be changed. The maximum length, whether or not a snake can die, whether or not a food spawns, how many snakes, and so on can all be changed to get different behaviors. There are 4 behaviors the snakes can take on as well, none, random, wander, and sequence. Depending on the behavior, snakes can automatically seek out food, or keep wandering forward indefinitely. Combining different snake behaviors and game rules generates a variety of musical sequences. See this playlist for a tutorial and many examples of how this script can be used.

There are no prerequisites other than a monome norns. This script supports nb which you can use to download and install diffrent nb voices to use with the snakes if you get tired of using the built-in rudiments synthesizer. This script supports typing keyboard controls and monome grid controls.

NORNS CONTROLS

selected snake:
E1: select snake
E2: speed
E3: turn snake
K2: toggle food view / snake view
K3: cycle snake behaviors

food view:
E2: ← down, → up
E3: ← left, → right
K3: place/destroy food
if two player mode is on
E2 turns next snake (+1)

slithering behaviors:
1 none: turn with ENC3 only
2 random: random snake turn (whimsy)
3 wander: turn towards closest food
4 sequence: seek food in order placed

GRID CONTROLS

poke the grid to place/destroy food!

KEYBOARD CONTROLS

select snake, select view:
1 select snake 1
2 select snake 2
3 select snake 3
4 select snake 4
TAB toggle food view / snake view

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-pit-orchisstra-779ad12.json

Then send OSC to 127.0.0.1:7777, for example:

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

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

MIDI controls

15 controls, each with its number, its range and the name to send

JSON

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

Limitations

Source: the Lua source of the norns script pit-orchisstra by postsolarpunk (entzmingerc/pit-orchisstra at 779ad12), 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 10 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. 12 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.
