A stereo four tap delay with feedback
PAUs:
1
This is a simple stereo 4 tap delay algorithm with delay lengths de
fi
ned in milliseconds (ms). 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. The taps are summed and added to the dry input
signal through a Wet/Dry control. The delayed signal from the “Loop” tap may be fed back to the delay
input.

Left Channel of 4-Tap Delay
The delay length for any given tap is the sum of the coarse and
fi
ne 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
fi
ll in the measure with interesting rhythmical patterns. Setting tap levels allows some
“beats” to receive different emphasis than others. The delay lengths for 4-Tap Delay are in units of
milliseconds (ms). If you want to base delay lengths on tempo, then the 4-Tap Delay BPM algorithm may
be more convenient.
