[sdiy] analog pitch shifter circuit?

[HOSHUYAMA]

Happy new year to all,

Schematics of an analog pitch shifter are at Mark Hammer's site:

   http://ampage.org/hammer/files/AnalogHarmonizer.ZIP
   http://hammer.ampage.org

The schematics are useful to get to understand how a pitch shifter
works.  However, it looks too complicated to build for the quality.

Obviously, almost all the comercially-available pitch shifters are
digital including all the Boss products.  To learn more about pitch
shifters, I'd suggest to read an AES paper by an E-mu engineer (or
founder?).
