Suboctave generator - 4013?

[Tony Allgood]

I think Steve's idea of a sine sub octave is a worthy goal. I reckon you
could do this easily. Three resistors to add your sub-oct square with
your saw of your VCO, to get a lower octave saw. Bit lumpy, but OK. Then
bung it through the one transistor full wave rectifier triangle
generator a la minimoog, and you've got your triangle. Four diodes and
one resistor and you have your sine (ish) output.

I started to do something like this a while ago, using a discrete
flip-flop too. Never got any further than the breadboard, but the
general idea worked well enough.
