GROWL
Pressing the
GROWL
tablet to
"ON"
creates a
kind of phase
mod-
ulation,
and
the
VIBRATO
effect
is
obtained. This
VIBRATO
effect differs
from
the
VIBRATO
effect
added
to
the
VCO
on
nuance.
The Modulation Speed
is
controlled
via
the
knob (~/nj)
of the
Modulation Generator
in
the
same
way
as
the
VIBRATO
of the
VCO,
and
the
Modulation Depth
is
controlled via the
GROWL
knob.
(2)
WAW
Pressing the
WAW
tablet to
"ON"
produces
the
WAW
effect
which emerges automatically
upon
touching the key.
These
GROWL
and
WAW
effects
depend
strongly
on
the position
of the
slide
control
knob
for
the Cut-Off
Frequency.

ADSR
When
this
tablet
is
at
"ON"
position, the voltage of the
ADSR
envelope
is
supplied to the
VCF.
So, the
Filter
works
with the
VCA
simultaneously,
and
very
inter-
esting effects
can be obtained.
The
effects of
GROWL,
WAW
and
ADSR
for the
VCF
are
controlled by the
knobs
of the
VCF
SENS
panel section.
