[sdiy] PLL examples

[Colin Raffel]

That one is a good example, but I personally like the slightly more  
complex one here:

It is an article from a magazine, and it has no distortion circuit  
and lots of room for features and improvement.  I always thought it  
would be interesting to put a pulse wave into the trigger in so that  
it tracked at any rate-sort of like a sample-pitch-and-hold-it for a  
guitar or any instrument.
