Laser Delay:
Laser Delay is a tempo based delay with added functionality, including image shifting, cross-coupling, high
frequency damping, low frequency damping, and a LaserVerb element. Separate left and right controls are
provided for delay time, feedback, and laser controls. Parameters associated with Laser Verb in a combination
algorithm begin with ÒDlyÓ or ÒLsrÓ.
The delay length for each channel is determined by Dly Tempo, expressed in beats per minute (BPM), and the delay
length (Dly Time L and Dly Time R) of each channel is expressed in beats (bts). The tempo alters both channel delay
lengths together. With the tempo in beats per minute and delay lengths in beats, you can calculate the length of a
delay in seconds as beats/tempo * 60 (sec/min). Since KDFX has a limited amount of delay memory available
(usually 1.5 seconds for Laser Delay), selecting slow tempos and/or long delay lengths may cause you to run out
of delay memory. At this point, each delay will pin at its maximum possible time. When you slow down the tempo,
you may find the delays lose their sync.
The laser controls perform similarly to those found in LaserVerb (see FXAlg# 911 in this book), and affect the laser
element of the effect. The LsrCntour changes the laser regeneration envelope shape. Higher values increase the
regeneration amount, and setting it to 0% will disable the Laser Delay portion completely turning the effect into a
basic delay. LsrSpace controls the impulse spacing of each regeneration. Low values create a strong initial pitched
quality with slow descending resonances, while higher values cause the resonance to descend faster through each
regeneration. See the LaserVerb section for more detailed information.
Delay regeneration is controlled collectively by the Dly Fdbk and LsrCntour parameters since the laser element
contains feedback within itself. Setting both to 0% defeats all regeneration, including the laser element entirely.
Increasing either one will increase regeneration overall, but with different qualities. Dly Fdbk is a feedback control
in the classic sense, feeding the entire output of the effect back into the input, with negative values polarity-
Algorithm Reference-78
Sets the user interface mode for controlling each of the 4 chorus LFOs.
Controls the relative phase between left channel LFOs and right channel LFOs. In
Dual1Tap mode, however, this parameter is accurate only when Ch Rate 1 and Ch Rate 2
are set to the same speed, and only after the Ch LFO cfg parameter is moved, or the
algorithm is called up.
These control the amount that the output of the chorus is fed back into the input.
Sets the user interface mode for controlling each of the 4 ßange LFOs.
Controls the relative phase between left channel LFOs and right channel LFOs. In
Dual1Tap mode, however, this parameter is accurate only when Fl Rate 1 and Fl Rate 2
are set to the same speed, and only after the Fl LFO cfg parameter is moved, or the
algorithm is called up.
These adjust the phase relationship between the corresponding LFO and the internal
beat clock.
