[sdiy] Capacitors in Moog ladder filter

[Tim Heffield]

Hello all,

I have a question about the four caps in the Moog ladder filter.  Looking
through all my old documents and on the web I see values that range from
0.022uF to 0.1uF for the the four caps that create the poles.  It seems to
me that this would just raise or lower the resonant freq for a given CV.
Does anyone know if there is more to it than this?  I noticed that the
Mini-Moog filter started out with 0.068uF and someone changed it to
0.027uF...was the cutoff frequency to low?  EFM seems to use 0.1uF on all of
his filters.
