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.
