Yamaha CS-80 - Attack Time; Decay Time; Release Time

[31
]
ATTACK
LEVEL
-
(Black) With
AL set at ^
(down) there is no effect.
Moving
AL up to
+5
and
then playing a note causes
the
sound
to
get
"thinner"
(less fundamental
and
more harmonics) and
to
then
move back to
the sound you have set
with
the
HPF
and
LPF
sliders, it is as
though you
moved
the
HPF
and
LPF
sliders up past
the ''steady"
setting
and
then
brought them
down together.
[32]
ATTACK
TIME
-
(Black) The A slider
adjusts
how long it takes for
the filter
envelope to
move from
the "fattest"
sound
to
the
"thinnest"
sound (these
points
being
set by
the
I L and/or
AL sliders).
SHORT
(slider down) causes a
fast
move that
sounds
li
ke a
"blip/
whereas LONG (slider up)
causes
a
gradual change
in
tone.
[33]
DECAY
TIME
-
(Black)
The
D
slider
adjusts
how long
it
takes for
the filter
envelope
to
move
from the
"thinnest" sound
to
the "steady"
sound
set
with
the
HPF
and
LPF
sliders.

RELEASE
TIME
-
(Yellow)
The R
slider adjusts
how long
it takes
for
the
filter to
return
to the IL
setting
after
you
let
go
of
the key or keys.
If
the
IL
slider
is
set at
^
(down),
then
R
sets
how
long
it
takes
for the
filter
to
return to
the "steady"
setting after
you release
the key.
If IL
and
AL are
both
at
^,
then
R
has no effect.
By
experimenting
with the VCF
envelope, you
will find that
many useful
effects can be
achieved,
including whistle and
rushing
wind. Brass sounds are
greatly
enhanced
by
the
use of
IL and
AL with
moderate attack
and decay
times.
To
get a
very
sharp
"blip" for
extremely
percussive sounds, set
AL
up
to
+5
and set
attack
and decay at
the
shortest
time
(down).
You
will
also
find
that the VCF
envelope and
VGA
envelope
can be manipulated
together
to
get
still
more variations in effect.
