PhaseDelayArray has three effect units chained together.
The first unit consists of a sequential array of vibrating (oscillating) reverberation sections. The oscillations can be tiny or huge. The reverb depth can be tiny or huge. The overall effect can be subtle or HUGE. And, it can create a pretty big range of sounds.
The second section is a modulation effect. It takes the output of the PhaseDelays and whips it around, or up-and-down or back-and-forth.
The final section is a feedback unit with the possibility of a lot of delay (up to 5 seconds). The mix section allows you to tap into all this strangeness in four different places.
