1. PLAYING
PATCHES
The
assign
buttons
(P.34) are
used to call
up the parameters
which correspond
to the
basic
sound
elements
of a Tone
(pitch
of the sound,
frequency
elements,
volume,
changes
over
time,
and
effects).
These are
the standard
values for
how the
sound
changes
according
to time,
key
range,
and key velocity.
Using the
[a]
and
{W]
buttons,
you select
the
parameters
which
determine
how
such changes
are
made.

The
parameters
which
can be controlled
while
you are
playing
are divided
into the
categories
shown
below.

ir
Coarse
Tune
This
changes
the pitch
in halftone
units.
By changing this
pitch
parameter,
you can change
the
sound program.
You
can
change the
quality
of the sound
by shifting
the pitch
in octave
units, or
by changing the
sound
range of
a single
Tone within
one
sound program.
Ik"
Fine
Tune
This
lets you
make fine
changes in the
pitch. It
is used to create
a detuning
effect
or make the
sound thicker.
For
example,
you can
use it to
reproduce
a honky-tonk
piano sound
by sightly
changing
the pitch between
the
Tones
of
two
piano
sounds.

Parameters
•
Cutoff
This
changes the
cutoff
frequency
of the TVF. It
is useful
for creating
dynamic
changes
in the brightness
of the
sound.
It can
also, completely
change
the timbre
of the
sound
by
altering
the
brightness
of each
Tone. A growling
effect
can
be created
by moving the
Parameter
Slider slightly
back
and forth.
i>:
Resonance
This creates
a characteristic
sound by emphasizing
the
frequency
elements
around the
cutoff frequency
of the TVF.

Level
This lets
you adjust
the volume
of the sound. When
a Patch consists
of several
Tones,
the character
of the
Patch as
a
whole
can
be altered
by
changing the
relative
volume
balance of the
Tones.
For example,
when
the attack
and decay
portions
of
a sound
are made
up of
separate
Tones, the
quality of the
attack
and decay
portions
are altered
according
to
the
Tone whose
level
is changed.
