The Magnus phase shifter

[Haible Juergen]

	>This circuit is almost the same as the Chroma sawtooth mix.

	>Quick description: The Chroma has a comparator, positive input
	>grounded, negative input has an equal mix of sawtooth and the PWM
	>control voltage, and the result is a resistor mix of the comparator
	>output, the PWM control voltage and the sawtooth.  
	>
	>But the Chroma mixes in twice as much sawtooth because the goal
isn't
	>a phase shifter but a mix of the original sawtooth and the
	>phase-shifted sawtooth for a thicker sound.

Is the Chroma circuit on the web somewhere ?
