4x4 Neotrellis arduino USB midi controller

by LydiaNeko on Thu Nov 07, 2019 5:12 pm

I'm currently racking my brain over how to program a Neotrellis board to output midi to Ableton/Max for live. I'd like to use it as a small Monome but would be happy with basic USB over Midi output at the moment. I'm using an Arduino Uno which might not be ideal and following this guide:

https://www.instructables.com/id/Arduin ... ontroller/

The problem is nothing happens when I press the buttons. I believe this is because its designed for the older Trellis? I've run the basic program for Neotrellis and the buttons and lights all work fine.

Please help

Hi LydiaNeko,

Maybe I should just start with what might be a stupid question for you.

Since you know you want a Trellis based USB midi controller would it make more sense to use the one of our Trellis options that was designed for this?

Thanks for your reply, my aim was to get a 16 button controller working with monome max software then build it into a custom controller. It might be a little bit easier to buy the M4 kit but also limited to button numbers and enclosure shape. I might have to step back and use a trellis instead it seems :(. Disappointing that the neotrellis doesn't accept the same code.

Does the UNTZtrument guide meet your needs? It is a 16 button MIDI / USB ready device based on the trellis.
