Vibrato
(a
frequently used
effect)
Vibrato
is
a cyclic pitch variation
produced
by
using
MG-1
to
modulate
the
SG
(VCO)
oscillator
frequency.
But
the vibrato
we
hear
in
real
voices
and instruments
is
more
complex;
it
has
volume
and tone
color
vari-
ations
along with the
pitch
variation.
You
can
easily
add
these effects
by
using
MG-1
to
modulate volume
(AM)
and
cut-
off
frequency (FcM).
The
triangle
wave
is
the best
MG-1
wave-
form
for
a
conventional
vibrato
effect.
