A real rotary pot (or slider for that matter) cannot be synchronised to 
software automation without the addition of motors - which costs £££.

A rotary encoder (such as is mass produced for CE equipment) is 
comparatively cheap:  with the addition of software such a rotary 
encoder can synchronise to an external device (in this case PD or a DAW) 
without the need to adjust the physical fader/knob position.

If you wanted to use sliders/knobs with end-stops, you'd need a 
procedure in which the user wiggles the control until it matches the 
external device or (as I have seen) coloured lights to tell you how to 
move the control to achive synchronisation.  Some manufacturers have 
decided that this isn't a nice interface.
