Small update on this. I have finally built the first 5 units of the new version of the DECO Multi. To test it right now, I only have a SLIM version (those with PCB name ending in - 8 and it works great. It should work also with a -3 but this is to be confirmed yet.
The first 5 people on the list have been already contacted. As soon as I get more units I'll contact you via DM.
