FXAlg #131: 4-Tap Delay ¥ FXAlg #132: 4-Tap Delay BPM
Algorithm Reference-37
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.
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.
The Hold parameter is a switch which controls signal routing. When turned on, Hold will play whatever signal is
in the delay line indefinitely. Hold overrides the feedback parameter and prevents any incoming signal from
entering the delay. You may have to practice using the Hold parameter. Each time the sound goes through the
delay, it is reduced by the feedback amount. If feedback is fairly low and you turn on Hold at the wrong moment,
you can get a disconcerting jump in level at some point in the loop. The Hold parameter has no effect on the
Wet/Dry or HF Damping parameters, which continue to work as usual, so if there is some HF Damping, the delay
will eventually die out.

Wet/Dry The relative amount of input signal and delay signal that are to appear in the Þnal effect
output mix. When set to 0%, the output is taken only from the input (dry). When set to
100%, the output is all wet.
Out Gain The overall gain or amplitude at the output of the effect.
Fdbk Level The percentage of the delayed signal to feed back or return to the delay input. Turning
up the feedback will cause the effect to repeatedly echo or act as a crude reverb.
HF Damping The -3 dB frequency in Hz of a one-pole lowpass Þlter (-6 dB/octave) placed in front of
the delay line. The Þlter is speciÞed for a signal passing through the Þlter once. Multiple
passes through the feedback will cause the signal to become more and more dull.
