These two
envelope generators
control
the "contour"
(or
(Ganges
over
time,
in
terms
of
the
sound's
attack,
sustain,
decay,
and
other
dynamic
characteristics) of
each programmed
sound.
The
VCF EG
determines
how
the
timbre, or brightness,
changes
over
time.
The
VGA
EG
determines
how
volume changes
over
time.
The DW-6000
utilizes
advanced
6-stage
EG
modules
with
"break
point"
ami
"slope"
rate
parameters
in
addition
to
the conventional
attack,
decay,
sustain
and
release
parameters. Six

ATTACK
(Rate)
Controls
how
long
it
takes
for
the
volume
or cutoff
fre-
quency
to
rise
from
zero
to
its
maximum
level
after
a
note
Is
played
on
the keyboard.
DECAY
(Rate)
Determines
how
long
it
takes
for
the
volume
or cutoff
fre-
quency
to
fail
from
its
maximum
attack
level
to
the
break
point
level.
BREAK
P.
(Break Point
Level)
Determines
the
level at
which volume
or cutoff
frequency
i^ops
dropping
during the decay,
if
this
Is
set to
the
same
^
value
as
the sustain
level,
then the envelope
becomes
a
conventional
ADSR
type
(as
if
It
had no
break
point or
slope
parameters).
SLOPE
(Rate)
Determines
how
long
it
takes
for
volume
or cutoff frequen-
cy
to
change
from
the
break
point
level
to the sustain
level.
Note
that
if
the
break
point
is
lower than the sustain
level,
then
the
slope functions
as a
second
attack.
If
the
break
point
Is
higher than
sustain,
then slope functions as
a second
decay.
