Circles

Circles consists of lib/libCircles.lua, the sequencing engine and the circles.lua script that uses the engine.

circles.lua

The circles script allows you to move a cursor around on screen using ENC 2 and ENC 3. Pressing KEY 3 will place a new circle at the cursor point. KEY 2 will remove the circle at the cursor point. Holding KEY 1 will remove all circles after a confirmation step. ENC 1 adjusts the cutoff frequency of the filter.

Placed circles will grow with each MIDI tick. This means that it will stay in beat with whatever else you have going on.

Circles will burst when they hit another circle or when the get too big. When they burst, they make sound. The sound they make depends on their x, y position on the screen and how big they are when they burst.

The pitch is determined by their x coordinate, with lower pitches on the left and higher pitches on the right.

The timbre is determined by their y coordinate, currently connected to PWM of the PolyPerc engine.

The size determines how long the sound will last. Larger circles will sound out for longer.

There are also a few parameters to adjust under the KEY 1 parameters page. Play around with those.

v1.6.3
  • Fixed PSET save/load: circle layout (positions, radii) and cursor are now saved alongside each PSET. Previously only menu params were persisted, so loading a PSET appeared to do nothing to the composition.
  • Updated param group/separator IDs to current norns API.
v1.6.2
  • Fixed midi channel out setting (Thank you @xbow!)
v1.6.1

Minor update to add midi continue support.

  • Added two new params; midi continue device and midi continue mode
    • Midi continue device lets you choose which device to listen for "continue" messages from; This allows you to choose a different midi device for "continue" messages than the device you're sending midi out messages to
    • Midi continue mode lets you choose if new "continue" messages always start playback or toggle so you can use it as a play/pause button
  • Grouped new params in "midi continue" group
v1.6

This is a pretty major update under the hood. Because of that I took this as an opportunity to update some of the param IDs. This means that existing PSETs will probably result in unexpected behavior.

Before updating, if you have any saved PSETs that you rely on, I'd encourage you to write down the settings so you can recreate them after updating.

  • Finally switched from using the old-school beatclock to the new hotness, clock.
  • Added midi-in transport controls; circles will now start/stop when the midi leader starts and stops.
  • MIDI out device shows name in params menu
  • Updated order of outputs param list; This will probably cause issues with any existing PSETs
  • Cleaned up params menu by grouping some params
  • Added new "step division" param

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-circles-a711dcd.json

Then send OSC to 127.0.0.1:7777, for example:

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

From Claude or any MCP client, the osc-bridge mcp server exposes this driver as norns_circles: 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 circles by jakecarter (JakeCarter/circles at a711dcd), 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 12 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.
