Important part:
3x 3P3T Switch: mouser: 612-1003P3T1BM1QEH
Important INFO: the Jack Hole Audio Out must be changed (drilling) to the panel border side otherwise the switch and jack are too close and will not fit in a correct alignment.
BOM:
normally you don't need the TL074 and the resistors around.. look in the schematics - its only for the CV and Audio "Mixer" - which isn't needed here.
Wiring:
the following wiring do not match with the schematics ( I didn't used this wiring !!) please look in the schematic as described
Schematic:
(the wiring was used by me for the Triple LPG - but you must turn the switch 180degrees that it match with the panel silkscreen)
Tip:
I used 10KA Potentiometers for the bottom mixer, I just connected from each LPG output (output jack) the signal to the bottom mixer poti, an 1K pullup resistor on the wiper
