OK will do. It will be rough drawing as I don't know much about the circuit diagram protocols.
As a starter for you - I built a test bed to work out how each item worked with MMjoy. Together, that covered 9 momentary buttons, 1 "On-None_On" toggle and a rotary switch (3 switch points) all connected to Shift Registers. In the end I have decided to drop the Rotary. I built the button matrix for the 2 encoders and their buttons. And last was a standard pot. This was the test bed and final box will be 3 pots, 2 Encoders/buttons with a total of 32 buttons.
Like to thank debolestis for his SR boards - love them.
This was a project to learn on as I will try and build a set of rudder pedals next! That will be a challenge.
