The amplitude of the saw feeding the delay time CV determined the amount of the shift. I think. It was a long time ago; I'd have to wire it up again and try it. I did the same thing with a very old Korg digital delay back in the 80's, too. (Wow, was it really that long ago...? Is it really 2005...?)

I think I understand what you mean. is that going from
a really tiny delay (milliseconds long) then slowing
it down in small increments via the downward shape of
the saw?
