Strictly speaking, a pitch shifter is different than a frequency
shifter. Pitch shifting maintains the harmonic relationships,
frequency shifting mangles them as it spreads them.
Frequency shifting is hard to do precisely, but I've personally never
heard of a VC pitch shifter. Maybe some of the Lexicon or other rack
effects boxes which do pitch shifting have a VC input, but they are
digital anyway.
Which exactly were you interested in?
