[sdiy] Frequency shifted from BBD?

[houshu at muj.biglobe.ne.jp]

Hello Didier,

A set of schematics of BBD based pitch shifter is here:

Please check Wacky harmonizer (an article from a Japanese magazine).
As discussed here, cross fading seems to be a problem.

I recently re-read the section in Barry Klein’s Electronic Music 
Circuits on bucket brigade devices and noticed a brief mention of using 
them as a frequency shifter by modulating with a ramp wave.
He acknowledges that there will always be an audible glitch and some 
noise issues.
I experimented with this idea a little to minimal success, but curious 
if anyone else has tried this or seen it used in interesting ways.
