Here's one that I was referring to earlier from the PitchFactor Presets: Other Effects thread. I'll add some proper screenshots for the QuadraVox variations and Resonator experiments when I get them all together.

Mix = WET: 50
Pitch Mix = A10+B10
Pitch A = A: UNISON
Pitch B = B: UNISON
Delay A = D: 310 ms.
Delay B = . A . B . C . D
(encoder) = QUADVOX / TMP: OFF
Depth / Key = (any) N/A
Speed / Scale = (any) N/A
Xnob = C: UNISON
Ynob = D: UNISON
(EXP PED Heel) = D: 310 ms.
(EXP PED Toe) = D= 1240 ms.
Nothing earth-shattering here. This is simply my nod to one of the settings in the classic magnetic drum echo unit. The Quadravox algorithm doesn't provide for any feedback, but that's something you can derive from a downstream delay pedal. It does allow for useful spacing between delays, and here, the four 'playback heads' are equally spaced.
Expression Pedal:
The pedal is set up to quadruple the maximum delay time of the original (Toe position). For the adventurous, add Pitch A, B, C, & D to – 1 oct or – 2 oct., for a pitch-shifting 'tape stop' effect. As the delay time gets longer, the pitch of all four voices will drop along with it.
