[sdiy] Rick Jansen's Moog ladder filter design question...

[Jean-Pierre Desrochers]

I'm about to build the modified Moog ladder filter you posted here:

http://dropmix.xs4all.nl/rick/Emusic/Moog/moogvcf_schematic.gif

I would like to change the resistor R15 2k37 1% for a 1k 1% 3300ppm tempco
but this will change the overall
A3 opamp gain and screw up the 1v/oct ratio on input called "KOV"
and all the other CV inputs.
Since I don't know the exact mv/oct value this schematic needs at Q1 base
for a good oscillation tracking, can you help ?
I think I'll just have to also change both P3 & R17 values right ?
But to what values ?

Thanks !
