Hi all,

Something I've noticed about the feedback control on phasors - when using negative feedback, it sounds best when the phasor output is inverted before mixing it with the dry signal, but when using positive feedback, it sounds best if you DON'T invert the phasor.

So, attached is a handy 'lil phasor control circuit that uses one knob to control feedback from negative to positive, and automatically switches the phasor output to an inverted signal when the feedback is negative. The circuit is the yellow modules. Use the red module to sweep from negative to positive.

I tried a simpler approach, using a morph group to control both the phasor feedback knob and the INVERT button on the 2-ch mixer, but it makes an annoying 'pop' when it switches. The crossfader with a lagged logic pulse is smoother. Enjoy!
