Here is one channel of the SP-4DP. I used 100K sliders so the values for the High/Low resistors are based on that with the calculated output ranges to be approximately 0-10V and 0-5V (5% resistors and slider's tolerances made this approximation). The 150K and 20K resistors could be changed for a trimmer to adjust exact ranges. As you can see, a very simple circuit. The sliders could be any resistive element.

Thanks dude, this is simple but efficient, nice work !
And another question, is 0 to 10v useful ? Or 0 to 5v is enough generally ?
All the best,
