PWM SPEED
LEVER
Determines the
speed of pulse
width modulation
when
the
WAVE
selector
©
is
set to
PWM. The more
this control
is
set
towards
the
"F" end of
its
scale,
the faster the
PWM
speed.

LFO (LOW
FREQUENCY OSCILLATOR)
The
LFO
can be used
to
modulate the
VCO
or
VCF
to create periodic
variations in
pitch or tonality.

LFO SPEED
LEVER
Determines the
frequency of the
LFO. The more
this
control
is
set
towards the
"F" end of
its
scale,
the faster
the
LFO
speed.

MODULATION WHEEL
Determines the degree of modulation applied to either the
VCO
or
VCF.
No
modulation
is
applied
when
this
wheel
is
set at
"0".
Roll-
ing
the wheel
upward
causes increasing
modulation depth.
®
VCO/VCF SELECTOR
Determines whether modulation
is
applied
to
the
VCO
or
VCF.
Applying modulation to the
VCO
creates vibrato-like effects,
while
modulation the
VCF
can create
wah-wah,
growl,
and an extensive
variety
of other
effects.
Applying modulation to the
VCF
produces a periodic shift
in
the
VCF
cutoff frequency.

PITCH VARIATION
©PITCH BEND WHEEL
This control can be used to create
sudden pitch variations
as
you
play. This permits creation
of effects similar to
choking a
guitar
string.
Pitch
can be
varied
over
approximately one
octave.
©GLISSANDO
LEVER
Creates a step-wise (1/2-tone
steps)
glissando
between notes played.
Set towards the
"L" end
of
its
scale this
control
produces
a slow,
fowing
glissando,
while
set
towards
the
"S" end of the
scale a
more
continuous portamento-like
slide
is
produced.
