2. Patch Editing Using the Knobs
(2) Try Changing the Tone with the Knobs
ot the proper controls selected, locate the knob
OPE. FILT.
ady have values set for these basic
oups for ENVE zR
and VIBRATO editing. Each of the 200 Original Tones
parameters (he value when the knob is at its central position).
The changes made here can be stored in memory as Patch Data (<r P.3-14).
So. lets get down to some knob-twisting and see what happens!

Changing
the
Envelope
(Attack,
Decay,
Release)
ATTACK]
This
sets
the
amount
of
time
from
the
start
of
the
sound
io
when
it
reaches
its
maximum
level
Rotating
the
knob
counterclockwise
(from
the
center
position)
decreases
the
amount
of
time
(faster).
and rotaiing the knob clockwise increases the attack time (slower).
DECAY This adjusts how quickly the sound
Rotating
the
knob
counterclockwise
(from
the
center
position)
will
decrease
the
decay
time
tasteri,
will decrease (decay) from its maximum level io the Sustain level.
and rotating the knob clockwise increases the decay time (slower).
*
The
Sustain
level
is
also
something
that
you
can
specify
for
each
Original
Tone
(<r
P.3-2).
RELEASE This determines how long the sound will continue after the string itself has stopped vibrating,
Rotating the knob counterclock
wise (from the center position) will decrease the release time (foster),
and rotating the knob clockwise increases the release time (slower).

You
can
control
three
elements
of
the
envelope
on
the

the
Attack.
Decay
and
Release.
These
eiements
can
all
be
adjusted
using
the
front

knobs.
This
lets
you
control
the
entire
