an inverted

beginning

rapid decay (for
an
up-
ward sweeping
effect).
n_
a square wave
{for angular, alternating
sound,
like
a trumpet
trill
or
a
rapidly
picked pair of
mandolin
strings).
NOISE
white
noise (for breath or
a
raspy sound).
EXT
whatever
line-level
(OdBm)
signal
is
applied
to
the external input
jack will affect
the
VCO.

sliders (C.

below);
if
nothing
is
connected to the
external input,
this
position
may
be used
as
an "off"
mode
for
the
whole sub
oscillator
section.
B.
SPEED
(white) affects the
speed
{rate) of the
sine,
sawtooth and square waves, but has
no
effect
on
noise or
the external
input. Set the
lever
up
for
slowest speed
and down
for fastest
speed.

VCO
(white)
varies the pitch of
any notes
you
play
by modulating
the Voltage Controlled
Oscillator with the
FUNCTION-selected
wave-
form. At slower speeds, the
sound
is
that of
a
vibrato. Faster
speeds
produce
a
resonance
that
resembles
ring
modulation.

VCF
(green)
modulates
the Voltage Controlled
Filter,
thereby varying the
tonal
character (over
tones) of any notes that are played.
At
slower
speeds, the
sound
is
that of an automatic
wah-wah
(especially
if
RESONANCE
[6] is
used). Faster
speeds yield unusual
effects,
particularly
when
a
square or
sawtooth
wave
is
selected for the
FUNCTION.

E.
VGA
(gray) applies
the
modulation
to the Voltage
Controlled Amplifier, varying
the
volume
of any
notes that are played.
At
slower speeds,
the
sound
is
that of a
tremolo. Faster speeds produce
beating
or pulsing effects.
NOTE:
Initially,
the
best
way
to hear the effect of the
Sub
Oscillator
is
to
choose
a
slow
SPEED,
pull the
VCO
lever
down
for
maximum
modulation, and
then select
each
FUNCTION
waveform. Repeat
the
same procedure
for the
VCF
and
VGA
levers.

TOUCH RESPONSE SECTION -
These
levers
modify
the
sound
according to
how
you
play the key-
board (dynamic
control). The
two
left-hand controls
are
related
to
the
Sub
Oscillator
Section
[8)
,
as indi-
cated.
The
BRILLIANCE
and
LEVEL
levers are in-
dependent
of
the
Sub
Oscillator. All levers produce
their
designated effect only
when you
press hard
on
the
keyboard; the
amount
of
effect
is
determined by
how
hard
you
press
a
key after
it
hits
bottom,
and by
how
far
the
Touch
Response
lever
is
pulled
down.
A.
VCO
(white)
varies
the pitch of the
sound up and
down
for
adding
vibrato to
a
given note
or chord."
