BRILLIANCE -
(Green)
BRILLIANCE
allows
you to
increase
or
decrease
the
amount
of
harmonics
(overtones) for
any
sound, whether
preset
or
patched.
Setting the lever
down
creates
a
brighter sound. Setting
the
lever
up produces
a
muted,
more mellow sound.
This
level affects
the
entire
keyboard. The nominal
lever position
for all
patches
is
centered.
[6]
RESONANCE
-
(Red)
RESONANCE
creates
special
tonal
effects,
such
as
"twang" and "wah." The
exact effect of
RESONANCE
depends
on
the
BRILLIANCE
[51 setting.
Set
RESONANCE
for
maximum
(up)
and
very
gradually
move
the
BRILLIANCE
lever
toward you
with the other hand.
Continue moving
BRILLIANCE
all
the
way
forward while playing
a series
of
notes.
Repeat
this exercise using several different preset
patches.
Now
experiment with
several controls.
Play
a
chord and
set
BRILLIANCE
and
RESONANCE.
Try
different
TRANSPOSITION
settings,
and
readjust
RESONANCE
and BRILLIANCE.
Colored
area is all
the
frequencies
in
the
"Raw"
patch
when
lever at
nominal.

BRILLIANCE-
LOW & HIGH-
(CS-60
ONLY)
-
(Green)
BRIL-
LIANCE
LOW
and
BRILLIANCE HIGH
allow you
to
balance the brightness across the
keyboard
range.
There
is
no abrupt change wheie one
lever's effect
ends and
the other lever's effect begins,
although a transition
occurs
somewhere
near
the middle
of the
keyboard. In
fact,
the
LOW
and
HIGH
levers
operate
on
a
smooth
curve
(see illustration).
BRILLIANCE
LOW
produces
more
effect
gradually as notes further below the middle
of
the keyboard
are
played, and, conversely, BRIL-
LIANCE HIGH
produces
more
effect gradually as notes
further
above the middle of the keyboard are played.
Both
levers
add
to the effect of the overall
BRILLIANCE
lever [5]
.
Play Clavichord,
string.
Funky and
Piano
patches,
adjusting the
KEYBOARD CONTROL
BRILLIANCE
LOW
lever.
BE
SURE TO PLAY A
SCALE
FROM
THE
BOTTOM TO
THE TOP OF THE
KEYBOARD
AS
YOU
EXPERIMENT.
Notice that
this lever affects
only the
lower portion of the keyboard, with
more
effect
toward the lowest
notes.
Repeat
the musical
example,
this
time adjusting the
BRILLIANCE HIGH
lever.
The
typical
acoustic instrument
is
less brilliant in
the lower
registers
and more
brilliant in
the higher
registers, as
shown.

SUB OSCILLATOR SECTION
-
This section
can be used to create effects such as vibrato,
wah-wah,
tremolo and others
through modulation of
the
VCO,
VCF
and
VCA.' The
FUNCTION
slider
selects the
type of
modulation (the
waveform)
for
variations
in
effect,
and
the
SPEED
lever
determines the modulation
rate.
The VCO,
VCF
and
VCA
levers
determine
the
amount of modulation, and
may
be used
individually or
in
combinations. For
the CS-50,
with
the lever
down,
there
is
no
effect,
and
with
it
up, the
depth
of the
effect
is
maximum. The
CS-60 operates so effect
is
maximum
with
levers
down. These
controls
may
be
used to
modify
the
sound
of any of the patches,
whether
preset or of
your
own
selection,
and
their
effects
apply equally across the entire
keyboard
range.
A,
FUNCTION
(black)
Use
this
switch
to select:
A,
a
sine wave (for
smooth,
up and down
modulation).
a sawtooth wave with
rapid beginning
'
s
" and slow decay (for a
downward
sweep-
ing special effect
sound).
'VCO,
VCF
and
VCA
refer to
Voltage Controlled
Oscillator.
Filter
and
Amplifier.
These
change
the pitch,
harmonic
struc-
ture
and
level, respective//, as
discussed further
in
Sections
III
and
V.
