I'm sorry, not faders but potentiometers (technically it's the same thing :whistle: )
But xOSC isn't as easier as it looks like, on the video you can see only 2 or 3 "widows" but in reality there are 12 "windows", look at the attached pictures (Functions 3xOSC, Potentiometer 3xOSC and Legend)
Because the problem is if I use only 20 potentiometers (exemple), if I turn Volume or another function on the same window at 70%, if I go to another window and I turn the same potentiometer to 25%, when I return on the first window, volume will be 25% and not 70% because the resistor value has changed, so I have not other choice that using 1 pot => 1 function... Perhaps rotary encoders will work, I don't know...
