What it does
Chaotic Phaser built from scratch using Brick-Wall Filter
A variation on the "phaser theme", this one is built using a chaotically time-varying band-(stop)-pass filter (the Controllable Brick Wall 4 block). The first Control Input is the instantaneous lower edge frequency of the filter, which, in this example, is driven by a signal derived from the Chaotic Control Generator (the intervening Control Clipper and Control Gains are merely to amplify the output of the Chaotic generator from the range 0->1 to a meaningful frequency in Hz). The second Control Input is the upper edge frequency of the filter, which, in this example, is always some factor larger than the lower edge frequency (by virtue of the Control Gains). The third Control Input is the the gain of the filter, which, in this example, is set to a constant (via the Constant Control Generator).
You can experiment with different types of sweep signal for both the filter edge frequencies and the filter gain. Try changing all parameter settings of all components to achieve a wide range of interesting phasing effects.
