In this video a short explanation about the Zener fix for the Grenar aswell which means a redesign of the pcb instead. So this also means a new build video. AND believe it or not a lower price! :D Not much but still... you got to take the small wins in this world ;)

As a side note (which is the most cool thing in the video...) someone asked on the discord if the Twigs firmware for Branches worked on the Grenar. Twigs is an independently made firmware for the Branches, which turns it into a VC factor/VC swing module instead. And it does work! The user Twig (not affiliated with Twigs firmware (I know, super confusing) helped me (again) to make this firmware work with old bootloader arduino nanos aswell, you can find the hex files for both versions on my github, but also check out the repo for Twigs here: github.com/arirusso/twigs
So I also show off what this cool firmware does, and then I made a new front plate specially designed for this firmware. Because there is a lot of information changed for what the controls do. You can buy the front panel in my shop: tindie.com/products/Sourcery/grenar-a-throughhole-version-of-the-mi-branches
Or download the Gerber files on my Github: github.com/SourceryOne/Grenar

I will also attend Dutch Modular Fest! Finally I get to go out there in the world and actually meet some of you :) Maybe see you there? 6 september in Rotterdam! Read more here: dutchmodularfest.com
