Soldering is a skill one acquires through practice. Don’t expect to be able to build complex devices on your first go. I have conveniently forgotten all the errors and poor soldering I performed as a youngster whilst learning the trade. 
well pin number 26 used by encoder 1 may be in conflict with the SPI display.
You won’t find any mapping for that configuration in the webconf tool. You will have to edit your own custom config:
‘ZYNTHIAN_WIRING_ENCODER_A’: “21,27,7,3”,
‘ZYNTHIAN_WIRING_ENCODER_B’: “26,25,0,4”,
‘ZYNTHIAN_WIRING_SWITCHES’: “11,23,22,2”
Thanks to all of you. It is indeed encouraging to get answers for unpatient questions.
hahaha thats what our kitche table looked like after my solder attacks…
Hey there,
thanks @le51 for pointing in the right direction.
All the encoders show difficult behaviour. After trying some variations I decided to go somewhat “minimal”.
The upper one lets me scroll through the layers, the below lets me scroll through the paramater section in the instrument.
Switch doesnt work on both.
For now i am doing the rest via Touch. Works so far…
