KDFX Algorithm Specifications
The feedback (Fdbk Level) controls how long a sound in the delay line takes to die out. At 100% feedback,
your sound will be repeated indeÞnitely. HF Damping selectively removes high frequency content from
your delayed signal and will also cause your 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 indeÞnitely. 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 your 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.
See also the versions of these algorithms which specify delay lengths in terms of tempo and beats.

Wet/Dry The relative amount of input signal and delay signal that is 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.
