simple 6 rotary encoder controller box

Hi ! I am looking for a building instruction for a simple controller box with just 6 endless rotary encoders. The end result should look similar to the doepfer pocket dial, but with less pots … when pressing on the rotary pots they also have a click “on/off” function with which I want to be able to change the bank …  Actually I am really just looking for a suitable wieringdiagram, I would be happy about any advice on this topic, thanx ! regards benni 

You are looking for a stripped down MB64E with only 6 encoders and 6 switches:
