Working on a dual SVF and during my testing I noticed something that I haven’t before so I’m not sure if it’s a quirk or something wrong. With the filter at self resonance (either one), it will continue to resonate at a setting above 56 at a lower volume, is this normal?
If you are referring to a ‘bleed’ of the self oscillation tone through the VCA even when no note is played, this is a known quirk ; a 2.2M resistor between pin 2 of IC3 and a -5V point can fix it.
and indeed it does. Thanks!
