Shepard and pitch shifting

[Rene Schmitz]

Hi list,

I just wondered why these two topics are discussed seperately!
My attempt to archeive pitch shifting would be the same as trying to get 
constantly rising pitch. I would use several delays with rising/falling
delay length, 
and VCAs to blend these singals in and out, so no pops would be heared. So
I think 
it can be done in the analog domain, but the setup would be enormous, like
a shepard generator whose saw outs determine the delay-time (i.e.
samplerate) and whose triangle outs determine the amplitude at the output
of the delays. 
Hmm, that would be 8 VCAs 8 VC-Delays and a shepard generator!
Maybe it is possible to get away with 2 or 4 delays and control signals 180
or 90 
degrees out of phase (?)

Bye
