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.
