PITCH
1(3
Pages)
Pitch related
parameters of
the
Tone
are set
on
this
page.
^
Pitch Shift
Coarse/Fine
This determines the basic pitch or tuning
at
which
notes
will
sound.
Coarse and
fine tuning controls are also
available
in
the
Performance
settings,
but the parameters
in this
section are separate controls used for creating the
basic sounds. For example,
you
can use
these controls to slightly detune the pitch of
two Tones
relative to
each other
to create a chorus
effect,
making
the
sound
thicker
and
more
animated.
It
is
also possible
to create a
chord by playing
one key
if
the pitch coarse parameter of
more
than
two Tones
are
set
appropriately.
y^
Keep
in
mind
that
using these
controls
changes
the
pitch
that
you
hear, but
has no
effect
on
the key
number
of
the
keyboard. Therefore,
the
key range
position
and
the
key
number
data transmitted via MIDI
OUT
are the
same
regardless
of
the
setting
of
these
pitch
coarse/fine parameters.
-^
Random
Pitch
Since, this
randomly detunes
the pitch for
each
note played,
it
is
particularly effective for reproducing the sound
of a
fretless stringed
instruments and
percussion instruments.
-k
Pitch
Key
Follow
The
pitch of
the
JV-80
is
changed according
to the range
in
which
keys are played.
The
key
C4
is
the center (or 0)
and
the pitch variation
in creases as
you
move
away
from C4.
Therefore, the pitch for
C4
is
the
same
regardless of
the key follow
setting.
Normally,
the
key follow parameter should be
set
to 100.
A
key follow
setting of
results in
no
pitch
change, or
ail
keys playing the
same
pitch.
This
setting
is
useful for
producing
transient sounds,
like that
of
the
hammers
on
piano
strings.
-^ Envelope
This
makes
changes
in
the pitch
over
time, within the range
set
by the depth parameter.
If
you
find that the pitch
doesn't
change
as
much
as
you want
it
to,
even
when
the
envelope
is
set to
a high value,
you
can increase the depth.
On
the other hand,
when
you want
to set the pitch to
change
in
minute
gradations,
even though
the pitch
change
itself
is
narrow,
set the
depth
to a
low
value.
When
simulating
the
sound
of a
human
voice or choir, a
more
realistic
sound can be obtained by
making
the
initial
phch
slightly
lower
than the
main
pitch.
These
parameters can
also
be used
to imitate acoustic
wind
instruments
like
the Japanese shakuhachi,
the pitch of
which
often
fluctuates
according
to
the player's
blowing
technique.
i^
Envelope Time Key
Follow/Velocity
Sensitivity
These parameters allow you
to
control
how
the
time of
the entire
envelope changes according
to the
key
position (the
standard or center
key
is
C4)
or
the
playing
strength.
This
is
useful for
changing
the pitch
by key
range or playing
strength, especially
when
simulating tuned percussion
instruments.
