Blacet's have an input which will allow you to transpose up and
down an octave, depending on if the input has a +1 volt (or
above) signal -or- a -1 volt (or below) signal at that input.

I think it has to do with the type of synthesis one does. Keyboard
performaers I think really prefer this octave switching feature,
while people who do the type of music which freely goes
inbtween the 1/2 step tend to prefer a full range pot.
