[sdiy] Book on analogue filter design

[Richard Atkinson]

Aaron,

Many thanks for pointing me to this magnificent resource! I will
listen to your lectures carefully. The patent section is brilliant!
Here it is, straight from the horse's mouth - Moog, ARP, Oberheim and
Yamaha filters :)

Interesting that ARP filed for a patent on the same 4 pole cascaded
integrator filter that Roland used. I wonder which came first...
