UniVibrator

Mix = WET:50

Pitch Mix = A10+B10

Pitch A = A: UNISON

Pitch B = B: UNISON

Delay A = 1 ms.

Delay B = 2 ms.

(encoder) = HMODLTR / TMP: OFF

Depth / Key = DP: – 10c

Speed / Scale = SPD:  40

Xnob = RAMP-DN

Ynob = FBK:  5

 

(EXP PED Heel) =  DP: -10c   SPD:  40

(EXP PED Toe) = DP: -30c   SPD:  80

 

This is about as close as I could come to a Univibe feel.  More 'Vibrato' switch position than the phasey Chorus position.  With a negative Depth setting, the sawtooth LFO is moving slight pitch variations in opposite directions.  I used that to simulate the wobbly, asymmetric sine LFO in the original.  Tiny delay times in each pitch shifter with minimal regeneration add to the complexity.

Expression Pedal:

The amplitude of the Univibe LFO increased as the speed gets faster.  The expression pedal simulates this with higher depth.  Of course, we're not simulating the distortions of the unique circuitry and LDR design.  You'll have to add some of that at the input signal here.
