Parameters
These parameters allow you
to
detennine
how
the
perfonnance data from the
JV-80
keyboard
is
processed
in
the
transmit zone of each
Part,
before
it
is
transmitted
over
MIDI.
"A"
Since
the
performance
data
from
the
JV-80 keyboard can be
split
according
to
the
key range
and
transmitted over
MIDI,
different external
sound
sources can be played separately
depending on
the range.
1^
Another
operation of these parameters, the
transmit
transpose
function,
lets
you
change the note
number
that
is
transmitted via
MIDI, by
a
certain
amount
relative to
the note played on the JV-80.
For
example,
you
can
set this
value
to
one octave lower
(or higher) to
allow playing
the
connected sound source
in
a
range
that
would
normally be
outside of the
keyboard.
You
can
also layer octaves
of
the
same
sound program,
or
set
up
a
chord
to
be played
when
you
press a single key.
^
Transmit
velocity
max
level curve/sensitivity/leve!
These parameters allow you
to
change
how
loudly or
softly the
MIDI
-connected external
sound
sources play
in
response to
changes
in
your
playing technique.
This
is
possible
through processing of
the velocity data
from
the
keyboard
for each transmit
zone
before
it
is
transmitted via MIDI.
In
order to
keep
this
change
in
volume
or
dynamics within a
certain range,
use
the
maximum
level
parameter. This compresses the velocity data
from
the
keyboard
that
is
transmitted
over MIDI, making
it
less
than the actual velocity played.
The
maximum
limit
of the
velocity after
being processed
is
set
by
the
maximum
level.
By
setting the sensitivity to a
value between
and
32,
the
minimum
limit
can
also
be
set.
You
can program
the
JV-80
to switch
between two
external
sound
sources
(depending on
how. strongly
you
play the
keyboard)
by
setting
the sensitivity parameters
to
+32 and
-
32
for the
two
transmit zones.
(Fig.
1
)
For example,
when
you wish
to
compensate
for
an uneven
playing technique,
such
as playing
more
strongly with
your
right
hand than your
left,
you can
split
the
two
transmit
zones by key
range.
Then
select
the appropriate
velocity
curve so
that
the velocity reaches a high value quickly
for the
left
hand,
even though
the
keys
are played
softly;
also
set
the sensitivity to
around
to
20.
For
the right hand,
select
the velocity
curve so
that
velocity doesn't
increase
even
when
the keys are played
strongly,
and
set the sensitivity to less than 32.
Compress
the velocity
to
the
desired degree using
the
maximum
level
parameter.
