[sdiy] simple vcf

[Dave Krooshof]

I googled a week ago for a filter mentioned here
and came about a file called "c3389pdf.pdf"
(do a google on that and, see what it is.)
it's a VCF with VC resonance, a VCA and a VC panning.
it only needs a few caps and buffers to run it.

But the question is: is a 3389 any good?


I used to think I liked the steeper filters better.
But I came to realize I like the 12dB/O filters
better then the 24dB/O ones.
Current favourite is the 6 dB/O output of a
24 dB/O filter. Nice resonance and not
completely dead simple sinusoid output.
But then again: I use LPFs to emphasis harmonics
rather then taking them away.
