What
is
the Patch
Edit
mode?
The Tone
is
the basic building block
for sound programs, and
the
JV-80
is
capable of
making
various kinds of
sounds.
A
Patch,
on
the other hand,
is
the basic
unit
of sound which
is
stored in
memory
and
called
up
for playing.
A
Patch can be made by
using
a
maximum
of
four
Tones
together.
When
creating a Patch,
it
is
helpful to look
at
it
as
more
than
just
sounding
several
Tones
simultaneously, but
rather as
making
a single
sound by
judiciously layering
the Tones.
The Tone
parameters of
the
JV-80
correspond
to
the
various
characteristics of
the
sound
elements (timbral quality
of
the sound,
its
frequency,
its
volume, and
the
ways
of changing them),
the
sound of
the internal
sound
source
differs
depending on
the
settings
of
these parameters.
The
main
work
in crafting
sounds
with a synthesizer
is in setting
and
adjusting these parameters.
However,
there are also other parameters
that are used
to
determine Patch names
and
effect settings
in
the Patch Play mode. These
parameters,
along with
the
Tone
parameters,
make
up what
are called
Patch
parameters. The
operations
for setting the
Patch parameters
are referred to as Patch
Edit operations. This
means
that
Tone
edit
operations are included
in
the Patch
Edit
mode. There
are four groups of
Tone
parameters
for
a
Patch parameter; only
the parameters necessary
for the Patch need be
set.
The
unnecessary groups of
Tone
parameters do
not
sound
when
the
Tone
switch parameter
is
set to
OFF.
The Tone
parameters
make
it
possible
to
take a sound and
apply various
functions
in
order
to
subtly
alter,
or
"synthesize"
it
into a completely
new
sound.
The
structure
of
the
Tone
is
shown
below.
