A stereo eight-tap delay with cross-coupled feedback
Allocation Units: 2
This is a simple stereo 8-tap delay algorithm with delay lengths defined in milliseconds (ms) (#133), or in tempos
and beats (#134). The left and right channels are fully symmetric (all controls affect both channels). The duration of
each stereo delay tap (length of the delay) and the signal level from each stereo tap may be set. Prior to output each
delay tap passes through a level and left/right balance control. Pairs of stereo taps are tied together with balance
controls acting with opposite left/right sense. The taps are summed and added to the dry input signal through a
Wet/Dry control. The delayed signal from the ÒLoopÓ tap may be fed back to the delay input. The sum of the input
signal and the feedback signal may be mixed or swapped with the input/feedback signal from the other channel
(cross-coupling). When used with feedback, cross-coupling can achieve a ping-pong effect between the left and
right channels.

The delay length for any given tap is the sum of the coarse and fine parameters for the tap multiplied by the
DelayScale parameter which is common to all taps. The DelayScale parameter allows you to change the lengths of
all the taps together.

A repetitive loop delay is created by turning up the Fdbk Level parameter. Only the Loop tap is fed back to the input
of the delay, so this is the tap which controls the loop rate. Usually you will want the Loop delay length to be longer
than the other tap lengths. Set the Loop delay length to the desired length, then set the other taps to fill in the
measure with interesting rhythmical patterns. Setting tap levels allows some ÒbeatsÓ to receive more or less
emphasis than others.

The delay lengths for 8-Tap Delay are in milliseconds (ms). If you want to base delay lengths on tempo, then the 8-
Tap Delay BPM algorithm may be more convenient.

The feedback (Fdbk Level) controls how long a sound in the delay line takes to die out. At 100% feedback, the sound
will be repeated indefinitely. HF Damping selectively removes high-frequency content from the delayed signal and
will also cause the sound to eventually disappear.
