Combination Algorithms [Ò+Ó]
Algorithm Reference-71
Flange:
The flangers are basic 1-tap dual flangers. Separate LFO controls are provided for each channel. Slight variations
between algorithms exist. Some algorithms offer separate left and right feedback controls, while some offer only one
for both channels. Also, cross-coupling and high-frequency damping may be offered in some and not in others.
Parameters associated with flange control begin with ÒFlÓ in the parameter name. A general description of flanger
functionality can be found in the Flanger section or this book, FXAlgs #154-155.
In addition to the LFO delay taps, some flangers may offer a static delay tap for creating through-zero flange effects.
The maximum delay time for this tap is 230ms and is controlled by the Fl StatDly parameter. Its level is controlled
by the Fl StatLvl parameter.

Delay:
The Delay is a basic tempo based dual channel delay with added functionality, including image shifting and high-
frequency damping. Separate left and right controls are generally provided for delay time and feedback. Parameters
associated with a delay effect in a combination algorithm begin with ÒDlyÓ.
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 these delays), 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. Because of this, when you slow
down the tempo, you may find the delays lose their sync.
Delay regeneration is controlled by Dly Fdbk. In some combinations, separate left and right feedback controls are
provided, while in others there is a single control for both channels.
Dly Image and Dly HFDamp are just like the HFDamp and Image parameters found in other algorithms. Not all
delays in combination algorithms will have both of these parameters.
