settings the early reßections are seamless. It is adjustable from 0.00 to 2.00, with 1.00 being
nominal for the given Room Type.
Density controls how tightly the early reßections are packed in time. Low Density settings
group the early reßections close together, while higher values spread the reßections for a
smoother reverb. It is adjustable from 0.00 to 4.00, with 1.00 being nominal (and usually optimal)
for the given Room Type.
Expanse controls the amount of late reverb energy biased toward the edges of the stereo image.
A setting of 0% will bias energy towards the center. Moving away from 0% will bias energy
towards the sides. Positive and negative values will have a different character.
Build adjusts the envelope of certain portions of the reverb. Positive values speed up the
envelope, and negative values slow it down.
Size Scale changes the size of the current room. Altering this parameter will cause a subtle
coloration of the reverb. It is adjustable from 0.00 to 4.00, with 1.00 being nominal (and usually
optimal) for the given Room Type.
InÞnDecay, when set to On, causes the reverb tail to decay indeÞnitely. When itÕs Off, the decay
time is determined by the Rvrb Time or LateRvbTim parameters.
Wet Bal (Wet Balance). Some reverb algorithms are actually two stereo reverbs in one, with each
one receiving a different mono signal. This balances the outputs of the two reverbsÑ0% means
they are being mixed equally.
Delays
There are two types of taps in the Multitap delays: The Loop tap, which can be repeated, and the
numbered taps, which play a single iteration.
Fdbk (Feedback) Level controls the repeating function of the Loop Tap. A setting of 0% means
there will only be a single delay, while a setting of 100% means the signal keeps repeating
without ever stopping.
Both types of taps are individually adjustable from 0 to 2.55 seconds. The Loop Crs and Tapn Crs
(n being the number of the tap) parameters set the coarse value of the loop in 20-ms increments,
while the Loop Fine and Tapn Fine parameters set the Þne value in 0.2-ms increments.
In Delay algorithms that use tempo to determine tap lengths, there is a Tempo parameter, which
can be set from 1 to 255 BPM or to System. The Loop Length and Tapn Delays are then
expressed in beats relative to that overall Tempo. See Tempo-based Parameters on page 15-25 for
more information about tempo control of KDFX parameters.
Hold is a switch that, when turned on, ÒlocksÓ any signal currently in the delay and plays it
until Hold is turned off. When Hold is on, no signal can enter the delay and Feedback is set to
100%.
Dry Bal (Balance) is the left/right balance of the dry signal. At -100%, only the left dry signal
goes to the left output, while at 100% only the right dry signal passes to the right output, and at
0%, equal amounts of the left and right dry signals pass to their respective outputs.
Tapn Level is the level of each numbered tap, from 0% to 100%, relative to the overall output of
the effect.
Tapn Bal is the left/right balance of each of the numbered taps. At -100%, only the left tap goes
to the left output, while at 100% only the right tap goes to the right output, and at 0%, equal
amounts of the left and right taps pass to their respective outputs. In some delays, pairs of taps
(1 and 5, 2 and 6, etc.) are controlled together as stereo pairs.
