A question to those who may know: Will the PolyEvolver keyboard have
the same knob-type/functions as the MonoEvolver?

Like, can only one knob be turned at a time?

Are the same 'pots/encoders' used as MonoEvolver?

I ask simply because regarding my MonoEvolver, I do believe that
someday its knobs will stop working correctly (because they already do
sometimes.)

If anyone knows any more specifics (pros/cons) of the PolyEvolver
Keyboard hardware please step up.  

Thanks,
Chris
