Delays
Delays repeat a sound a short time after it
first occurs. Delay becomes echo when the
output is fed back into the input (feedback).
This turns a single repeat into a series of
repeats, each a little softer than the last.
The Studio Delay features up to 2.5 sec-
onds of stereo delay and offers a built-in
ducker that attenuates the delay output
whenever signal is present at the input.
This can be used to keep the original sig-
nal from being muddied up by delay
repeats.
The Digital Delay is the cleanest, most
accurate of the delay programs, with up to
5 seconds of mono delay and the built-in
ducking feature.
In the days before digital, delays were cre-
ated using a special tape recorder in which
the magnetic recording tape was looped,
with closely-spaced recording and play-
back heads. The delay effect was created
by the tape moving in the space between
the record and playback heads – while
delay time was adjusted by changing the
speed of the tape loop. Although very
musical-sounding, wow and flutter com-
bined with a significant loss of high fre-
quencies, and to some extent also low fre-
quencies, are all elements commonly asso-
ciated with tape recordings. The Tape
Delay offers up to 5 seconds of mono
delay.
This delay effect pans the delay repeats
from left to right, while the input signal
remains at its original (center) position.
Pong Delay offers up to 5 seconds of
mono delay time.
The Modulated Delay is enhanced by an
LFO (low frequency oscillator) that pro-
duces a chorusing effect on the delay
repeats. This is a great delay for guitar and
instrument passages that need that “spe-
cial something.” The Modulated Delay
features up to 2.5 seconds of stereo modu-
lated delay.
This delay effect emulates the old studio
trick of flipping a tape over, playing it back-
wards through a tape delay, and recording
the effect. The delays “build up” from softer
to louder – creating the sensation that the
delays come before the signal. Very cool
when used judiciously. Up to 5 seconds of
mono delay time are available.
Delay Controls
Time Range
Controls the length of the delay relative to
Tap Tempo. At the 12 o’clock position,
delay repeats are synchronous with the
Tempo light (represented by a Quarter
Note); lower values create faster repeats,
higher values increase the time between
repeats. Range 0-72. See Appendix on
page 39 for exact note values.
Feedback
Controls the number of delay repeats by
feeding the delay output signal back into
the delay input. This creates a series of
delay repeats, each slightly attenuated until
they become inaudible. Higher settings
create more repeats; lower settings reduce
the number of repeats. When this knob is
turned fully clockwise, it engages Repeat
Hold – delay repeats play back in an infi-
nite loop, but no further input signal is
introduced into the delay effect. Repeat
Hold is available only on Studio, Digital
and Pong Delay.
