KDFX Algorithm Specifications
Flange
The fl angers are basic 1 tap dual fl angers. Separate LFO controls are provided for each channel. Slight
variations between algorithms may 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 chorus control begin with “Ch” in the
parameter name. A general description of chorus functionality can be found in the Chorus section.
In addition to the LFO delay taps, some fl angers may offer a static delay tap for creating through-zero
fl ange 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.

Fl Phase Left and Right. These adjust the corresponding LFO phase relationships
between themselves and the internal beat clock.
Fl StatDly Sets the delay time for the non-moving delay tap for through-zero fl ange effects.
Fl StatLvl Adjusts the mix amount for the static tap. Negative values polarity invert the
static tap signal.
All other parameters Refer to Flange documentation. Parameters with a 1 or 2 correspond to LFO
taps organized as described above.
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, and laser controls. Parameters associated with Laser Verb in a combination algorithm begin with
Dly.
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 it’s
