The Sentient Machine is an LFO modulated resonant lowpass filter with two different voices: A standard wah sound and a special vowel type sound. At slow speeds it produces a spacey sweeping sound reminiscent of a phaser.

The vowel voice mode is achieved by modulating an additional filter that is tuned higher and sweeps in the opposite direction. It's a combination of filters sometimes referred to as a formant filter. This circuit uses PWM and CMOS switches as variable resistors insted of vactrols or jfet's, which gives a perfectly matched set of variable resistors and more accurate modulation at low resistances.

A great sounding pedal and fairly easy build for an inexperienced builder as me.
