PITCH
CONTROL
-
(Black) This
is
a concentric
control.
The
outer
ring
is
a
coarse adjustment that
tunes the
entire
keyboard up or
down
in pitch.
The
full
range of adjustment
is
about
1
octave,
and the ring
is
detented
in the center
for
normal
tuning.
The
inner
knob
is
a
fine pitch adjustment with
a
range
of
about
one semi-tone
(slightly less
on
the CS-50).
Nominal
position for both knobs
is
centered.
NOTE: To
obtain the
most
precise tuning to other
instruments:
a)
Press the
"FLUTE"
Preset
[3]
.
b)
Turn
off or set at
minimum
all
Sub
Oscillator,
Ring Modulator,
and Touch Response
effects.

RIBBON CONTROLLER
(CS-60
ONLY) -
This
is
a
velvet-covered strip that tunes the entire keyboard
up
or
down
in
pitch.
It
makes no
difference
where you
first
touch the ribbon;
you
just
move
up
or
down
from
that reference point, either
by
sliding
a
finger
along
the ribbon, or
by
holding one
finger in
place and touch-
ing
another
finger
elsewhere on
the ribbon.
Use
this
for expressive vibratos, string-bending effects,
chord
modulations,
whistles
or other unusual
effects.
When
the
CS-60
is in
SUSTAIN
I
mode,
the ribbon only
changes
the pitch while
you
are
holding
down
a key.
In
SUSTAIN
II
mode, the ribbon
will also
change the
pitch
during
the sustain (after
you
let
go of
the keys).
Experiment
to see
what
happens
when
you
let
go
of
the key and then the ribbon, and
vice-versa.
NOTE:
The range
of
upward
pitch slide
is
approximate-
ly
1
octave
if
you
start at the
left
of the
ribbon and
move
to the far
right.
The
range of
downward
pitch
slide
is
much
greater; by starting
on
the
right
of the
ribbon
and moving
to the
left,
you can move
the high-
est
note on the keyboard
down
to
a sub-audio
frequency.
