 99 (vol. 20, no. 11) Nuts and Volts (pages 25-27).  It uses the 566 
 as a tunable noise source, but also shows how the chip can be used
 to get a 20 Hz to 20Khz range by using a John Simonton trick 
 first described in Polyphony, Nov. 77, p.28-31.  I would love to 
 see a copy of that article.  The N&V article also shows Terry Mikulic's 
 exponential converter from Electronotes (v. 5, No. 37, p. 2-4).   >>

I have re-drawn my own schematic of Tom's tunable noise source from Nuts and 
Volts.  If anyone wants to see it, please let me know and I will email the 
gif to you.  It's a nice little circuit.
