CONTROL
DESCRIPTIONS
O
Pitch
Bend/Chorus-Phase
Joystick
Left-right
movement
of
the
Joystick
varies the tuning
of
the entire
instrument
over
a range
of
±2
semitones.
The
Joy-
stick
is
"spring-returned"
to
its
middle
in-
tune
position,
for
convenient,
momentary
"pitch
bending"
effects.
Forward-backwards
movement
of
the
Joystick varies the "rate"
of
the
Chorus-
Phase
effect
(which
is
activated
using
the
Chorus-Phase
Selector Switches).
Speed
can be
varied
from
a
slow "Flanging"-type
effect to that
of
a
rotating
"Leslie"-type
speaker.
The
Joystick
remains
in
whatever
forward-backward
position
is
set
by
the
performer.
©
Chorus-Phase
Selector Switches.
These
switches determine
which
instru-
ment
voices (Percussive/Ensemble)
will
be
processed
through
the
Chorus-Phase
system.
Depressing
a button activates the
effect
for
the
designated
section
and
lights
the
corresponding
LED
indicator;
depress-
ing
it
again cancels
the
effect
for
that
sec-
tion.
When
the
STEREO OUTPUTS
1
&
2
are
being
utilized,
each
section's
processed
signal
is
returned
to
the
opposite output
from
the
unprocessed
signal,
creating en-
hanced
stereo
effects.
Oscillator
Tune
Controls.
These
controls
vary
the individual
and
overall
tuning
of
the
ES-50's
three
oscillator
systems:
Total
Tune:
Varies
overall
tuning
by
±2
semitones.
Tune
A/B:
Varies
individual
tuning
of
two
of
the three
oscillator
systems by
±2
semi-
tones. This
arrangement
allows the user
to
create extra "richness"
by
slightly
de-tun-
ing the three oscillators
from
each
other.
Tuning
indicators:
Twin
LED
lights
pro-
vide
visual
indication
of
the
amount
of
"detuning"
for
oscillators
"A"
and
"B".
The
LEDs
stop
blinking
when
the
designated
oscillator
is
in
tune
with the Master.
(NOTE:
STRINGS
I,
STRINGS
II
and
CHORUS
voices
must
be
"Off"
for visual
tuning.)
For best
results,
tune
the three
oscillator
systems
slightly
apart
from
each
other,
such
that
the
LEDs
blink
approximately
1-2
times
a second.

(Fc)
of
the
Voltage Controlled
Filter
(VCF)
associated
with
the
Ensemble
Sec-
tion's
BRASS

from

extreme
left
to
its

right
pro-

"French

ELECTRIC PIANO
Key
Click:
Varies
amount
of
a
percussive
"click"
sound
which occurs
for
each
key depression
on
the
ELECTRIC PIANO
Voice. This
effect
increases "penetration"
of
sounds,
par-
ticularly in live
performance
situations,
and
can produce a
"mallet"
effect
when
creat-
ing
"Vibes" sounds.
Tone
Controls
Rotary tone
controls are
provided
for
each
section
(Percussive,
Ensemble)
to
allow
variations
in
tonal quality
as
desired.
These
controls
are
designed
as "Boost
and
Cut"
type,
for
increased
effectiveness.
Volume
Controls
Individual
easy-to-use
slider-type
volume
controls
are provided
for
each
se-
ctions
output
to
facilitate
overall control
of
the
ES-50's output
level
and
balance.
If
the
optional
Korg
MS
-01
Control
Voltage Pedal
is
being
used
via
the
EX-
PRESSION
control jack
to
vary
the
ES-50's
volume
levels,
the
front
panel
controls
will
determine
the
maximum
level
achievable
bytheMS-01
Pedal.
O
Octave UP:
Raises
the entire
instrument's tuning
by
one
octave.
In
effect
provides
a
five
octave
span
to
PERCUSSIVE
voices,
and
a
six
octave
span
to
ENSEMBLE
voices.
