hello,

<< On an analog or digital delay you can pitch shift
the regenerated signal by adjusting the delay time. >>

Yes, this is true, though only one method.

<< It seems to me that an analog pitch shifter could
be created by using some BBDs. >>

But that's half analogue and half digital...and one
must pay careful attention to the gain stage to make
it sound good cause BBDs can be kinda "blah" in
general. Lo-fi, though I'm into that...

<< It would very similar to an analog delay except
there would be no signal regeneration. It would be
just as easy to create a voltage controlled digital
delay/pitch shifter. Boss has guitar pedals that do
this and the older BOSS-RPS10 was a fantastic Digital
Delay/Pitch Shifter with a 0-5v CV on the back! >>

The problem with digital is latency, especially when
working via CV (conversions). I have a "simpler"
(takes up more space though), analogue approach but
with a commercial design already in "prototype" I
don't think it'd be appropriate to share such a
circuit.

But I'll give you a hint, if you care to do some
research, look at some old radio equipment.

Thanks, Shawn Cleary
