Sample and
hold
will
randomly
percolate. Again,
experiment
with
different
modulation
speeds,
waveshapes, and
different
amounts
of modulation. Try modulation
with
a high
FILTER EMPHASIS
setting.
Change
the
CUTOFF.
Remember,
it*s
possible to
open
the
CUTOFF
control so
far
that
you
won't
hear
any modulation
effect.
If
you
start
adding
CONTOUR
shapes
to the
FILTER
while
it*s
being modulated from
the
LFO
or
some
other source (such
as
a voltage
pedal),
it's
possible to drive
the
CUTOFF
frequency
so high that
you won't
hear
any
modulation.
If, in
your
fiddling
around
with
knobs and
dials,
you
suddenly
get
no modulation,
turn the
CUTOFF
control counterclockwise.
If
that doesn't
help,
make
sure
you've turned up one
of the
three possible
MODULATION AMOUNT
controls
(the
MODULATION WHEEL
[2.3],
the
MODULATION

Q
Some
rules
of
thumb
about modulation:
Triangle waves
are used
to create vibrato
when
applied to the
oscillators at a rate
between about
5
and 20Hz.
Pulse
width modulation
is
useful for creating string
sounds,
which
require a
lot
of phasing and
motion
in
them,
it
is
also possible to
*'turn on''
and
**turn
off
an
oscillator
by modulating
its
pulse
width from
or
to
0%
(only the pulse wave
should be on
if
you
Ve trying to
do
this).
if
the
rate
is
slow
enough
while modulating an
oscillator(s),
you
can hear the waveshape
of
the
LFO. The
faster the
rate
of modulation,
the
more
clangorous
the sound.
When
modulating
the
filter,
it's
possible to
have
the
CUTOFF
frequency
so high
as to
not be
able to hear any modulation
at
all.
Square wave
modulation
of the
oscillators
is
used to
create
trills,
which
can be tuned with the
modulation amount
controls.
