Illustrates the bizarre effects achievable using a variable delay.
This is an extreme case of a time-varying delay . The core of the effect is the Controllable Variable Delay block which
implements the time-varying delay. This block has, in addition to the audio input, a control input (red) which is driven by a
modulating control oscillator (the Combo Control Generator block). In this example, the Combo Control Generator block
reads an envelope from an external text file ("twotone.txt") which modulates the delay length. In this way, you may specify
any arbitrary desired envelope by creating a simple text file (alternatively, you may use the built-in envelopes !).
Experiment with all the settings to explore the behaviour.
