STEREO PHASING
This effect is variable from an almost imperceptible
slow-moving phase shift, to a rapid pulsation. The effect
is created as follows.
The input signal is split up into right and left signals.
The right channel is delayed very slightly in relation to
the left channel. A third signal, placed in the center of
the stereo image, has its delay time modulated between
zero and the right channel delay time setting, by the
LFO. This means that the center signal will periodically
"арргоасһ" and "meet" the left and right channels
alternately, causing phase changes as it does so. This is a
totally controllable digital version of the original phasing
method: playing back the same signal on two tape decks
whose minute fluctuations in speed caused phase
changes—a rather haphazard method. The timing differ-
ences need to be very small, and on the REV? can be set
as low as 0.1 msec.
TREMOLO
The tremolo preset is adjustable from a slow once-every- `
ten-seconds roll to a twenty-times-a-second vibrato. It is
produced in virtually the same manner as the Chorus
preset, with the amplitude modulation emphasized (for a
deeper, more rapid modulation). Most conventional
tremolo effects use amplitude modulation and nothing
more, The other parameters of this preset add extra
richness and dimension, for a really modern, sophistic-
ated sound.
SYMPHONIC
Another effect based on the same modulation system
as the Chorus preset. This time, the delay time modula-
tion is more rapid and deeper, giving the effect more
movement and more width, to create an expansive,
spacious effect from any input signal.
SPRING |
Spring reverb, featured in many low-price reverbera-
tion devices, and often built into combo amplifiers or
organs, can add a pleasing, bright ambient quality to
high register instruments (lead guitar, flute) as well as
vocals.
ECHO ROOM
The authentic sound of the original echo device—the
Echo Room, where the sound was transmitted from one
end of a specially reflective room, and picked at the
other end by a mike. A long, rich reverb effect versatile
enough for all instruments.
STRINGS
The first of several preset effects specifically designed
for use on named instruments, though of course they
can be used for any purpose. They all feature the six-
"modes" described in preset 5, above. For a string
orchestra, the most natural reverb is found in older,
"medium" size concert halls, and this reverb type
program accurately simulates this environment.
ELECTRIC BASS A
This E/R1 type preset actually creates the fullness
and depth of a large reflex speaker cabinet of the type
used for amplifying a bass guitar. So with a "direct
injection" bass guitar you can achieve a rich deep sound
without the inherent problems caused by miking up
speaker cabinets, With this widely variable preset you
can simulate a variety of tube amplifiers and speaker
enclosures.

ELECTRIC BASS B
This E/R2 type program is more "live" than the previous
effect, and can add briliance and "spice"
funky bass riffs.
KICK
Superfast delays in this E/R1 type preset actively boost
the sound of a bass drum, adding a vivid, yet solid pre-
sence, ideal for hard and heavy rock.
SNARE .
With this reverb type preset, you can transform an ordi-
nary snare drum into a classic "wall of sound" effect
used in many rock recordings.
GATE REVERB
A common studio effect on contemporary recordings is
produced by linking up various effects units—reverbera-
tor, digital delay, noise gate, compressor—so that a
powerful reverb is produced, which suddenly cuts off,
instead of fading gradually. This E/R1 туре proqram
reproduces that effect, and is nothing short of astound-
ing when used on drums, creating an enormous sound
that does not overhang and cloud up the overall sound
of the band.
REVERSE GATE
Closely related to the GATE REVERB preset, this
program actually gives the impression of a reverse reverb
effect. The reverb builds in intensity before cutting off
sharply and dramatically.
PIANO
The impressive sound of a concert grand piano in an
ideal room setting can be created from virtually any
piano, by the judicious use of this E/R2 type effect.
ORGAN
With this E/R1 type preset it is possible to give an elec-
tronic organ the expansive, mellow sound of an old
"tube" organ with its large wooden speaker cabinets.
BRASS
Another useful E/R1 type effect, the BRASS preset
enables you to add punch and "sizzle" to brass instru-
ments, retaining their brilliance while expanding their
harmonic qualities.
GUITAR
An E/R2 type preset providing a mellow ambience that
will delicately enhance the tone of any fine acoustic
guitar,
HANDCLAPS
This short, sharp reverberation type effect adds an
almost metallic presence and fullness to handclaps,
for a truly contemporary sound.
LIVE REFERENCE
This E/R2 type preset simulates a "standard'' live atmos-
phere. The effect is of a small, yet live, resonant room,
elevating the tonal quality of any instrument or vocal to
a brilliant, powerfully ambient timbre.
