This out-of-phase pair of loops takes advantage of the differing range limits in the Pitch Cntrl parameter. As the loops drift out of sync, the Eventide pitch shifter models go 'back in time'. Pitch (in the feedback loops) starts at unison, then increases to 1/3 semitone, followed by 1-1/2 semitones up.

Phasing phrase loops drift in time, pitch, + shifter model & algorithm, with long decay.
Repeat switch folds in 200 ms. stutters of the audio currently looping in the buffer.
EXP PED adjusts Delay B time, type of algorithm, & pitch resolution / pitch range,
Overlapped parameter changes create 4-5 FX types (within loops) over pedal throw range.
