Dry Bal The left-right balance of the dry signal. A setting of -100% allows only the left dry signal to
pass to the left output, while a setting of 100% lets only the right dry signal pass to the
right output. At 0%, equal amounts of the left and right dry signals pass to their respective
outputs.
Hold A switch which when turned on, locks any signal currently in the delay to play until Hold
is turned off. When Hold is on, no signal can enter the delay and Feedback is set to 100%
behind the scenes. Hold does not affect the HF Damping or Wet/Dry mix.
Loop Crs The coarse delay length of the Loop tap. If the feedback is turned up, this parameter sets
the repeating delay loop length. The resolution of the coarse adjust is 20 milliseconds, but
Þner resolution can be obtained using the Loop Fine parameter. The maximum delay
length is 2.55 seconds (2550ms) for the 4-Tap Delay.
Loop Fine A Þne adjustment to the Loop tap delay length. The delay resolution is 0.2 milliseconds
(ms). Loop Fine is added to Loop Crs (coarse) to get the actual delay length.
Tapn Crs The coarse delay lengths of the output taps (n = 1...4). The resolution of the coarse adjust
is 20 milliseconds, but Þner resolution can be obtained using the Tapn Fine parameters.
The maximum delay length is 2.55 seconds (2550ms) for the 4-Tap Delay.
Tap n Fine A Þne adjustment to the output tap delay lengths (n = 1...4). The delay resolution is 0.2
milliseconds (ms). Tapn Fine is added to Tapn Crs (coarse) to get actual delay lengths.
Tap n Level The amount of signal from each of the taps (n = 1...4) which get sent to the output. With
the Loop Lvl control, you can give different amounts of emphasis to various taps in the
loop.
Tap n Bal The left-right balance of each of the stereo taps (n = 1...4). A setting of -100% allows only
the left tap to pass to the left output, while a setting of 100% lets only the right tap pass to
the right output. At 0%, equal amounts of the left and right taps pass to their respective
outputs.
Algorithm 132 4-Tap Delay BPM
In this Algorithm, the delay length for any given tap is determined by the tempo, expressed in beats per
minute (BPM), and the delay length of the tap expressed in beats (bts). The tempo alters all tap 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). IMPORTANT NOTE: KDFX has a limited amount of
delay memory available (over 2.5 seconds for 4-Tap BPM). When slow tempos and/or long lengths are
speciÞed, you may run out of delay memory, at which point the delay length will be cut in half. When you
slow down the tempo, you may Þnd the delays suddently getting shorter.
A repetitive loop delay is created by turning up the feedback parameter (Fdbk Level). Only the Loop tap is
fed back to the input of the delay, so this is the tap which controls the loop rate. Usually you will want the
Loop tap (LoopLength parameter) to be longer than the other tap lengths. To repeat a pattern on a 4/4
measure (4 beats per measure) simply set LoopLength to 4 bts. The output taps can then be used to Þll in
the measure with interesting rhythmical patterns. Setting tap levels allows some ÒbeatsÓ to receive
different emphasis than others.
