Effects and Effect Mode
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 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 ne value in 0.2-ms increments.
In Delay eects 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.
Hold is a switch that, when turned on, “locks” any signal currently in the delay and plays it until
Hold is turned o. 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.
Tapn Level is the level of each numbered tap, from 0% to 100%, relative to the overall output of
the eect.
Tapn 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 eects 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 eect has two feedback taps per channel as well as three independent taps, and also a
feedback diuser 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 o
feedback line 2, only allowing use of feedback line 1. 50% is an even mix of both lines, and 100%
(maximum) turns o line 1.
L Di Dly and R Di Dly adjusts the delay lengths of the diusers. Range is 0 to 100 ms.
Di Amt adjusts the diuser intensity. Range is 0 to 100%.
C Fdbk n Dly adjusts the delay length of the C channel’s nth feedback tap, fed back to the C
channel’s delay input. Range is 0 to 2600 ms.
