Mix = WET: 50

Pitch Mix = A10+B10

Pitch A = A:  UNISON

Pitch B = B:  UNISON

Delay A = A:  1/8

Delay B = B:  1/16

(encoder) = DIATONIC / TMP: ON

Depth / Key = (any) N/A

Speed / Scale = (any) N/A

Xnob = FB-A:  75

Ynob = FB-B:  75

 

(EXP PED Heel) = B:  1/16

(EXP PED Toe) = B:  1/2

 

Controls level of Voice A (Voice B) feedback.  The feedback delay length is Delay A or Delay B, whichever is longer.

The excerpt above (from the Diatonic section of the UM) explains the idea behind this preset.  In the default settings, this is just a rapid ping-pong delay with a somewhat long decay time.  But when you start to vary the delay times …

Expression Pedal:

By controlling the delay time in Delay B, the expression pedal shifts the feedback delay length between the 1/8 note static setting in Delay A, or the current expression pedal setting (if it's longer than an 1/8th note) in Delay B.  Active use of the EXP PED yields scratching & stuttering delay effects.  The feedback length remains sync'ed to tempo, but the changing divisions result in a very unique delay effect.
