PLAYING
PATCHES
-k
These
allow
you
to adjust the
change
in
the
sound over time
by
controlling the
envelopes applied
to
the
wave
generator,
TVF
and
TVA. By
shortening the
attack time,
you
can
emphasize the attack portion
of
the
sound.
By
controlling the
Envelope Level L3, you
can
make dynamic changes
in
the brightness
and "thickness" of
the
decay or sustain
portion of the sound.
•^
Pan and
Effects
This
lets
you
create a
sense of space and
movement by changing the stereo position
of each
Tone. For example, you
can
create the effect
of
a player
moving
around
the stage
by
continuously
changing the stereo position
of a solo
instrument
sound program. Three-dimensional
effects,
such
as
placement of sounds
in
the
foreground or echo can
also
be
obtained
by adjusting the
level
of the
JV-80's
built-in effects.
In
addition
to
the basic
parameters explained above, there are parameters
which allow
you
to
change
the
sound
according
to
how
hard
you
play the
keys or
what
range of the
keyboard
you
play.
With
the
use of these parameters,
you
can
eliminate harsh
high-frequency elements
in
a Tone, or
have an otherwise
silent
Tone
sound
when you
play
the
keys
strongly.
•1^
Both
the
MIDI send and
receive
channels
can be
set
in
the
Patch Play
mode
as
well.
However,
since
this
setting
is
determined
not
by
the
Patch parameters but
by
the
system
common
parameters, the MIDI channel
will
not
change even though
the
Patches are changed.
Because
of
this,
the
MIDI channels
must be
set with the
system
common
parameters
(P. 75).
In
the
Patch Play
mode, one parameter controls four
Tones.
However,
in
the
Patch Edit
mode
{P.7S),
which
will
be
explained
later,
several parameters
for
one Tone
are called
up
to
the display.
Because
of
this,
it
is
occasionally
difficult
to
see
the entire
structure of the Patch. Therefore,
it
Is
effective to
use
the
Patch
Play
mode
in
order
to edit
the Patch,
keeping the
balance
among
the Tones.
