Check out an issue of "Electronic Musician" or similar magazine, or
your local, large, electronic musical instrument retailer.  Look for
adds for or inquire about effects processors.

Digital Signal Processors have hit the commercial musical instrument
processing industry in a big way.  There are numerous widely-available
units which can do pitch shifting in addition to other common musical
instrument processing effects like digital echo, reverb, distortion,
overdrive, etc.

Most can be operated under computer control using MIDI (Musical
Instrument Digital Interface).
