Combiner

Combine 2-127* Grids into a virtual grid available to all scripts

What you can do with it
  • Combine smaller Grids into a standard 128 or 256 size.
  • Make non-standard layouts like 32x8 or a Grid with gaps.
  • Mirror Grids so two can play at once.
  • Set rotation (including 16x8 vertical) and LED 'intensity'.
Requirements
  • Norns 231114
How to use it
  1. Install from the Maiden project manager (or ;install https://github.com/dstroud/combiner)
  2. Enable the mod in SYSTEM>>MODS>>E3 (+ symbol) and restart.
  3. Edit your layout in SYSTEM>>MODS>>COMBINER>>K3.
    • First, arrange your physical Grids however you want.
    • Press column 1, row 1 to place the first Grid. It will detect orientation.
    • Add new Grids by holding the corner of any placed Grid and tapping an adjacent corner of the new Grid.
    • To change additional settings, tap the center of a Grid to select it and use E2 (navigation) and E3 (change).
  4. The virtual Grid will appear in appear to scripts on port 1 (default for most scripts).
Notes
  • Grids do not have to be added in SYSTEM>>DEVICES>>GRID. Only add them there if you want them to be available in addition to the virtual grid on port 1.
  • Any Grid that you touch while in the mod menu is "enabled" as part of the virtual Grid's pool of devices. Use K3 to toggle this manually.
  • K1+E3 enables fine editing of x/y offsets.
  • LED intensity is not supported on all devices.
  • If using a NeoTrellis, each device must have a unique name+serial in SYSTEM>>DEVICES>>GRID. This may require editing your .ino file and re-uploading the firmware.
To script authors
  • Sorry.
  • Mirroring can result in repeat key down/up events (e.g. if the same key is held on two Devices). Feel free to not care.
  • Combiner will call the grid.add callback when the virtual Grid changes so you can detect column/row changes with something like:
function grid.add(dev)
  cols = g.cols
  rows = g.rows
end

*Okay I've tested with 4 Grids. Prove me wrong.

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-combiner-3cbfb8a.json

Then send OSC to 127.0.0.1:7777, for example:

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

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

MIDI controls

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

OSC commands

Command Arguments Name to send
Param id: string, value: float /norns_combiner/param/{id}
Param {set} {id} set: string, id: string, value: float /norns_combiner/param/{set}/{id}
Remote key n: int, z: int /norns_combiner/remote/key
Remote enc n: int, delta: int /norns_combiner/remote/enc
Remote brd code: int, z: int /norns_combiner/remote/brd

JSON

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

Limitations

Source: the Lua source of the norns script combiner by modularbeat (dstroud/combiner at 3cbfb8a), 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 0 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. No parameter could be read from its source (it may add none, or add them through a library or at run time): reach its parameters with the base driver's /param/{id}. 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.
