Variable Bandwidth Filter (VCF2)
Contributor Norman Fay says:
1. By mixing the hi-pass and lo-pass outputs together, a variable
width notch filter is created. By turning the bandwidth control, the
sound goes from a very faint fixed phaser type of effect to complete
filtering out of the sound, with upwards and downwards filter sweeps
clearly audible. If you are fading out a part during mixdown of a
piece, doing this instead of pulling down your mixer fader creates a
startling "how did they do that" type of effect.
2. Mixing the two fixed bandwidth outputs with the dry signal
creates a pair of resonant-ish peaks in the sound without
overwhelming it. Adjust both bandwidth and frequency controls to
taste. At certain points you will find that almost ANY signal source
takes on an eerie "vocal" quality, especially if you apply lots of
reverb.
3. Mixing the lo-pass output with variable amounts of the two fixed
bandwidth outs gives a response something like a cross between
phasing and filter resonance.
VCF2 is also very pleasing to the ear, and I'd strongly recommend
anyone to add one to their Serge setup.

>From the above, you'll probably conclude that a MIX2 module is anessential add-on to the VCF2, and you'd be right. The sound of the
VCF2 is also very pleasing to the ear, and I'd strongly recommend
anyone to add one to their Serge setup.
