hi guys,

I was reading about the P3 and was wondering why pots were chosen to
control the P3 (those are pots, right ?). When loading a pattern,
wouldn't it be easier that the result of turning a knob just gave a
INC/DEC (endless rotary encoders), instead of an absolute value ? 

...but maybe the OS and the way the P3 is structured doesn't allow this ?

just a question...
