o
ENVELOPE
By
setting the
ENVELOPE
switch
to
ADSR,
the
envelope
voltage
produced by
slide
volume knobs
of
ADSR
is
supplied
to
the
VCF
to create very interesting
effects.
By
setting the switch to jT\
,
the slow
attack voltage
is
supplied to the
VCF. And
by
setting
toA_
,
an effect
similar to
WOW
can be obtained.
All
the envelope
voltages are supplied to
the
VCF
via
the
SENS
dial,
thus
ENVELOPE
is
inoperative
when
the
SENS
dial
is in
"O"
position.
o
GROWL
Sliding the
GROWL
knob
creates a
kind
of phase modulation, 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
RATE
volume knob
of
the
LFO.

VCA
(Voltage Controlled Amplifier)
o
ENVELOPE
ADSR:
When
switched
to
ADSR,
envelope
voltage produced by
ADSR
slide
knobs
is
supplied
to the
VCA,
thus volume
can
be changed
via
ADSR
curves.
SLOW ATTACK:
Switching
to
_TT
brings a
slow
rising
sound
such as
produced
by
a violin
or an accordion.
STACCATO:
Switching
to
A_
causes
a
Staccato-like
sound
(like
the
sound
of
PIZZICATO
playing
of
a violin)
regardless
of key
depression time. Percussive
effect can be
obtained
via
the
HOLD
dial.
SUSTAIN:
J~l
An
effect the
same
as
SUSTAIN
alone
in
ADSR
can
be obtained by switching
to_TT,
i.e.,
a
sound
is
produced
as
soon
as
the key
is
depressed
and
suddenly
stops
by
releasing the key.
c
HOLD
The
HOLD
is
a
note
memory
device,
and
the note
for the
key
depressed
is
continued
until next key
is
depressed even though
the
key
is
released.
o
TREMOLO
The
TREMOLO
works
to
supply
Tremolo
effect to the sound.
When
employing
sine
wave
('"nj) it
is
of the usual
Tremolo, and
for
saw-tooth wave
(KK) it
produces an
effect
like
the
Tremolo
playing of
a
Mandolin,
and
use of
symmetric
rectangular
wave
(ELI)
produces
a
continual sound.
These waves
all
operate
the
VCA.
The speed
of this
Tremolo
effect
is
adjusted by the
knob
of the
LFO.
