PERCUSSIVE SECTION
•
Voices
ELECTRIC PIANO: The sounds of
a
wide
variety
of Electric Pianos are created. The
Percussive TONE control will vary this
voice
from
a
"Vibes"
to a
metallic "Reed"
effect. The use
of
the
ELECTRIC PIANO
KEY
CLICK control will enhance the "per-
cussiveness" of the Voice. ELECTRIC
PIANO
can also
be
combined with the
HARMONICS voice, for an effective
"Vibes" Piano
effect.
PIANO:
Creates the
sounds
of Acoustic/
Electric
Pianos.
Use
this voice with the
Chorus- Phase System
at
slow speeds
to
produce a
"multiple piano string" effect,
which is particularly impressive in stereo.
CLAV: Renders
a
funky "struck string" ef-
fect,
popular in many styles or current
music.
HARMONICS: Creates "Bell-Chime-like"
effects 3 octaves above
fundamental tones.
Useful for "Celeste" effects, or to
add
bril-
liance and clarity
to
other voices.
•
Effects
SUSTAIN:
Cancels "damping"
of
notes
which
normally occurs following key re-
lease. The effect is the same as continuous-
ly
holding down the Damper pedal on
a
piano.
This switch
overrides
the
function of
any
sustain
footswitch connected
to ES-50
rear
panel "SUSTAIN"
jack.
Tremelo On/Off
-
Speed: Processes all
Percussive Voices through a variable
speed
"Tremelo"
(Amplitude Modulation)
effect.
The
speed
of
the
effect is
varied by
the TREMELO SPEED control
from ap-
proximately 0.5
-
8Hz.
ENSEMBLE
SECTION
These voices
utilize
up to
three separate
oscillator
systems
to
create rich orchestral
backgrounds.
•
Voices
BRASS: This voice
uses
a
double oscilla-
tor sound
processed through an "articu-
lated"
Voltage Controlled Filter (VCF), for
enhanced
realism. The VCF's Cutoff Fre-
quency
is front-panel variable (BRASS Fc),
to
produce a wide range of "Horn"
sounds.
ORGAN: A
Rock/Jazz Organ effect is
created using multiple oscillators and
multiple octaves. It is best used with the
CHORUS-PHASE effect,
which
can
create
variable speed "Rotating
Speaker"
effects.
Organ "Percussion" effects can be
created by
combining
ORGAN
with the
HARMONICS Voice in the
PERCUSSIVE
section. The Percussive VOLUME
and
DECAY controls act as Organ
Percussion
"Volume"
and "Length" controls, respec-
tively.
CHORUS:
Creates the sound of
a
large
group
of vocalists. This unusual voice is
best used with the Variable
ATTACK and
RELEASE controls, and with the CHORUS-
PHASE system at
slow speeds for in-
creased "ambience".
STRING I, II: The sounds of
an ensemble
of Violins,
Violas and Cellos are created
by
these voices. STRING
I
is a lower
16'
voice;
STRING II is an
octave higher
(8'), and
can be
combined with STRING
I
for an
expansive orchestral effect. The
CHORUS-
PHASE system can create stunning
"panoramic" effects of
a
large concert hall.
The richness of the sound can also be in-
creased by slight "detuning" of the
oscil-
lators using the TUNE
A &B
controls.
The use of the Variable ATTACK and
RELEASE controls offers many dramatic
effects, including
"delayed" strings
and
"split keyboard" effects (see Variable AT-
TACK/RELEASE). When combining String
Voices with
a
Piano Voice, the use of a
moderate amount of variable ATTACK
will
produce greatly enhanced realism.
•
Effects
Vibrato
Off: Eliminates Frequency
Modula-
tion (Vibrato)
effects applied to STRING
and
CHORUS voices,
thus adding a
"glassy", unmodulated sound
to
these
voices. The judicious
use
of the TUNE A&
B controls will create variable amounts of
"beating" effects between the three oscil-
lators.
Variable ATTACK/RELEASE: With
the
switch in the normal position, the Attack and
Release times (beginning and end of
each
note played)
are preset
for
fast
articulation.
With the switch activated, the Attack and
Release times
can be
separately varied
over
a
wide range
by
their respective con-
trols.
Exciting "Delayed" String/Chorus ef-
fects
are created by setting the Attack con-
trol at or near its maximum. Used in con-
junction with
a
"Piano" Voice,
every
key
depression will produce the
piano note fol-
lowed
by
the slower String note. If the key
is released quickly, the String
note
will not
occur. This powerful feature allows selec-
tive expression of String
versus Piano
sounds,
depending on how
the keyboard is
played. Notes played quickly ("staccato")
will produce Piano sounds only; notes held
down will produce an initial Piano note fol-
lowed by a sustained String note.
With
a
little
practice, you
will
be
able
to
create
"Split Keyboard" effects of sustained String
sounds combined with
percussive Piano
effects
. . . from one
keyboard!
Utilizing
a
longer Release Time via the
Variable Release control gives a
realistic
concert hall "ambience", since
each note is
sustained independently.
