[sdiy] Moog 911 ADSR and CEM3320 filters

[Tom Wiltshire]

Hi all,

I've done a few updates to my website:

http://www.electricdruid.com

There's a new page to describe a Moog 911 ADSR envelope generator  
clone that J-P Desrochers has done using my PIC code as a base. He's  
copied the exact logarithmic pot response of the original and done a  
front panel graphic. It's nice work.

I've also done a page comparing some CEM3320 filter designs that I  
found whilst looking into alternative circuits for my Pro-One. This  
includes the LPF, HPF, and BPF from the datasheet, as well as both  
filters from the Oberheim OB-Xa, and the Elka Synthex multimode  
filter. And the Pro-One's original filter, of course.

I hope someone finds this useful.

Regards,
Tom
