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.
