ok, that worked.

Neo Trellis → MIDI Controller → midigrid → Monome Grid for Norns
Meet trellicopter. Instructions on converting an Adafruit NeoTrellis 8x8 grid into a DIY Monome Grid for Norns.
I still can’t believe I actually got this to work (after all the soldering issues, code blip-blops, and what-have-you), but here we are. I hope this helps someone else!
Can you customise the device name?
I’d totally accept a PR if you can change the device name to trellocopter! (Only slightly joking here) If you changed generic_device at all you should create a new device and include generic device, then just override the bits you need to change. Have a look at some of the other devices like launchpad to get an idea.
As far as coming as close as possible to the “real thing” what do people think is the best option right now for a 64 grid? I’m only leaning towards the launchpad because its cheap and available, but if something felt more “nornsy” I’d go for it.
Reading through this thread I was wondering the same thing, I guess the only différence between a launchpad mini & neotrellis 8x8 are the extra rows of buttons of the launchpads. Doesn’t really matter if you use only one but if you use two to get a 128 I’d prefer to go the neotrellis route so I can have both of them side by side without a “gap” in between.
I think I’ll go the Launchpad route for now, and I’ll try to grab a grid when the new version comes out (apparently it might be a bit cheaper, which is great when ordering from EU).
You may know this already, but just to mention that
Midigrid is set up so that one Launchpad is rotated 90 degrees to make that gap minimal, and in practical terms it’s no real issue.
Didn’t knew that! I’m gonna look for two launchpad minis then!
Has anyone tried to connect a Launchpad Mini Mk3 with the Compass script?
When i add the known line
local grid = include("midigrid/lib/midigrid")
before line 12 in compass.lua i get an init error after restarting the script.
Would be great if alternative grids could work with Compass too.
Compass works partially for me with 2x Launchpad Minis Mk 3 and
midigrid, though for that reason I’m using
local grid = include("midigrid/lib/mg_128")
However, while the pads light up and move along the sequence lanes, button presses are registered extremely slowly with a lot of latency and the Norns Shield itself stops registering encoder or key presses either (Edit - since I typed that, the Norns flew through a bunch of activity, so with a substantial delay in triggering them).
Thank you very much. It works indeed with the include you mentioned and behaves also quite weird.
I just deleted my last message
Disregard that last, I think I discovered something.
Anyway, just made a PR, let me know if you see anything off!

Great - thanks for your help!!
FYI - I have copied the good work done on the MiniMk3 to allow my standard sized Mk2 to also rotate in this fashion. Thus, with two LP Mk2 (which is also RGB), you can also have the relatively unbroken line of 16 pads. Let me know if anyone is interested in the changes I made to my code for this, as second-hand Mk2s are even cheaper than MiniMk3s.
Can someone qualify which launchpad devices are classed as “rgb” ones?
I am just about to pull the trigger in some lp mini mk2 units… But if the lp mini mk3s are a lot better in terms of what they can display or if they have better compatibility, now is a good time for me to know.
Thanks for so much help so far
Mini Mk2 is Red/Green and the mini MK3 is RGB. Mini MK3 will give you the full brightness range and a better colour palette, but are likely much more expensive?
See my earlier comments on buying S/h launchpad minis…
Thank you for all your help, I have just read through the whole thread and whilst I am in intimidated a little… I have decided to go both feet in and ordered a lp mini mk2, thanks for all your help.
I did the same and got it working in 5 minutes. Dead simple. Good luck!
I was wondering if there are any cheaper alternatives to grids? I would love to be able to properly dive into some of the patches on norns which require it however I can’t quite splash the cash on another thing right now.
I would recommend checking out the adafruit neotrellis thread.
This thread might be a bit redundant as there are a good chunk of resources for this on a lot of fronts. The neotrellis grid is one, as well as the midigrid library which offers support for a pretty impressive handful of controllers. I would poke around the thread for the midigrid library as well as the norns: alternative grids thread.
