Effects Overview
Delays
There are two types of taps in the Multitap delays: The “Loop“ tap, which has a feedback loop
back to its input, and the numbered taps. The numbered taps can be single iterations or they can
repeat as part of a loop, but they do not have individual feedback paths.
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
Tap
n
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
Tap
n
Fine
parameters set the fine value in 0.2-ms increments.
In Delay effects 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
Tap
n
Delays
are then expressed
in beats relative to that overall Tempo.
Hold
is a switch that, when turned on, “locks” 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%. A
good parameter to control with a footswitch.
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.
Tap
n
Level
is the level of each numbered tap, from 0% to 100%, relative to the overall output of
the effect.
Tap
n
Bal
is the left/right balance of each of the numbered taps. At -100%, only the left channel of
tap
n
goes to the left output, while at 100% only the right channel of tap
n
goes to the right output.
At 0%, equal amounts of the left and right channels of the tap pass to their respective outputs. In
some delays, pairs of taps (1 and 5, 2 and 6, etc.) are controlled together as stereo pairs.
DelayScale
lets you change the lengths of all the taps together. Its range is 0 to 10x.
Note:
It is possible for the PC3A to run out of delay memory with over-generous settings of
DelayScale or very slow Tempos. Some Delay effects will simply go to a maximum value and
stay there, while in some, a calculation is made that automatically cuts the delay times in half,
thereby maintaining a relationship with tempo.
Complex Echo
This effect has two feedback taps per channel as well as three independent taps, and also a
feedback
diffuser for “smearing” the delays. Feedback line 1 feeds the signal back to the delay
input of the same channel, while feedback line 2 feeds the signal back to the opposite channel.
FB2/FB1>FB
is a balance control between feedback lines 1 and 2. 0% (minimum) turns off
feedback line 2, only allowing use of feedback line 1. 50% is an even mix of both lines, and 100%
(maximum) turns off line 1.
L Diff Dly
and
R Diff Dly
adjusts the delay lengths of the diffusers. Range is 0 to 100 ms.
Diff Amt
adjusts the diffuser intensity. Range is 0 to 100%.

n
th feedback tap, fed back to the
C
channel’s delay input. Range is 0 to 2600 ms.
