I built a minimal Zynthian with a Raspberry P3 B+ and I have to connect the 4 encoders… [Zynthian minimal....😉 - #3 by Lanfranco](https://discourse.zynthian.org/t/zynthian-minimal/7980/3)  
I found an MPC23008 chip in the drawer… so I do with this, as I did in the Zynthian I’m using now.  
Thanks again for the speed of your replies.
