Today, CV Joystick/Wheel in the case !
A mix with 2 schematics (joystick and wheel)
On one joystick i keep the spring inside to use more like a wheel.
All axes have Offset and Range pot
Wheel have a switch fore 1 oct or 5 oct (positive or negative)
it was long for me to calibrate it, but that’s it, really fun 
A video which after having listened to it again with a little atmosphere of K2000
