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.

Parameters
Available

Realtime Control
The
parameters which can
be
controlled while
you
are
playing are divided
into
the categories
shown
below.
l# Rtiih-rilatedlK
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.

TlnOTe-reiated 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.
\#Voiume-related Parameters
:M\i:-'
-k
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.
