The
Envelope
Curve,
Controlled
by
“Attack”,
Decay",
and
“Sustain”.
Every
sound
has
its
own
specific
variations
over
time.
That
is
to
say,
both
the
volume
and
the
tone
color
change
along
with
time
from
the
starting
point
of
the
sound
until
it
dies
out
completely,
Take
a
guitar,
for
example.
You
will
realize
that
volume
and
tone
color
differ
considerably
between
the
momenta
String
is
plucked
and
the
moment
just
before
the
sound
fades
away.
When
this
change
over
time
is
expressed
in
the
form
of
2
graph,
you
get
what
is
called
an
“envelope
curve"
or
just
“envelope”
for
short.
The
MT-400V
has
controls
for
“attack”
“decay”
and
“sustain”
which
allow
you
to
regulate
the
variation
of
the
harmonics
over
time®.
thus
providing
further
control
over
tone
color.
*
As
shown
in
the
illustration,
the
envelope
determines
which
har-
monics
are
heard
at
what
time.
For
example,
after
attack
is
com-
pleted
(the
ee
I
has
peaked),
the
sound
contains
the
greatest
number
of
harmonics
(f
—5f
in
our
case).
Then
after
decay
time
is
over
and
sustain
level
is
reached,
the
sound
will
only
contain
harmonics
f—3f.
*
Adding
a
‘‘Wah-Wah"
Effect
to
a
Sound
While
the
envelope's
attack,
sustain
and
decay
determine
the
change
in
tonal
color
from
the
time
the
sound
starts
to
be
heard
until
it
fades
away,
the
so-called
“wah-wah”
effect
causes
a
sort
of
grow!
by
changing
tone
color
rapidly
and
periodically,
*
Since
the
MT-400V
controls
the
inclusion
of
harmonics
in
a
sound
mentioned
above
opening
and
closing
the
filter,
this
function
is
called
“Fitter
Control”
