VCA
{Voltage Controlled Amplifier)

VCF LEVEL -
Adjusts the
amount
of
input
to
the
VCA
provided by the
VCO's
square wave, sawtooth
wave
and/or noise generators
and
filtered
by the
VCF.
(311
SINE
WAVE LEVEL -
Adjusts
the
amount
of
input
to the
VCA
provided by
the
VCO's
sine
wave
generator. Since the sine
wave does not go through
the
VCF,
it
may
be
mixed
in
any
proportion with the
VCF-processed
signals as
it
enters the
VCA.
132]
A —
{Attack
Time)
Adjusts
how
long
it
takes for
the
level
to increase to a
maximum
each time
a
note
is
played.
[33]
D
—
{Decay Time] Adjusts
how
long
it
takes for
the
level
to decrease
from
a
maximum
to
a steady
(sustained)
level
each time
a
note
is
played.
(34]
S
—
(Sustain Level) Adjusts the fixed
level
of
a
not that
is
steady (after attack
and
decay) so long
as a
key
is
held down.
135]
R
—
(Release
Time) Adjusts
how
long
it
takes for
the
level
to die to silence after you release a
key.
The
effect
is
like the sustain time provided
by
the controls
in
[10].
[36]
LEVEL -
(VCA
Level) Sets the highest
level
attained
by
the
VCA,
thus affecting the sustain
level
and the
maximum
attack
level.
If
VCF LEVEL
[30]
and
SINE
WAVE
LEVEL
[31] are
thought of
as
input
mixing
controls,
then
this slider serves
as
the
VCA's
master output
control.
