VCF/QUO nonlinearQ demo

this vid is a simple demonstration of the nonlinear resonance (nlQ) effect on this VCF. In the 1st half the nlQ pot is left at zero and the regular Q pot is turned from 0-max.
In the 2nd half, the reqular Q pot is left at max and the nlQ pot starts at max and is wound back.
This VCF is also a very effective quadrature oscillator and is part of the nonlinearcircuits drum panel, more info - http://nonlinearcircuits.blogspot.com.au/2013/03/drum-panel-8.html
