simulated echo with sub-audio AM

Patch flowchart	Description
	Simulated echo with sub-audio AM. A steady-state signal from an oscillator is patched to two VCA´s in series. Two different controlfunctions are used. VCA1 is controlled by a triggered envelope generator. This envelope determines the overall decay characteristic of the sound. VCA2 is controlled by a repetitive sawtooth function (a continually triggered ADSR will also do the work). This control simulates the echo characteristics in terms of speed (repetition rate) and "echo" shape. This is not a real acoustic echo but only a simulation using amplitude modulation.
