[sdiy] Good 24db/oct HP-LP-BP-Notch filter Schematics ?? Moog type possible consideration..

[Jean-Pierre Desrochers]

Hi list,

Thanks for all your good comments,
I think the topic is drifting a little...
Here is my first post question:

I'm looking for schematics of a good 24db/oct HP-LP-BP-Notch VCF.
All the filter modes outputs should be available simultaneously..
The only filter I found that do such things is the following:

http://www.analoguesystems.co.uk/modules/rs110.htm
But no schematic available...

--> If I'm willing to forget about simultaneous filter type outputs
--> my love for Moog ladder VCF sound would drive me to build
--> a VCF that would include Moog 904a, 904b & 904c (real 24db/oct).

Any suggestions welcomed.
Thanks.
JP
