It is
possible
to
set
the JX-1 to use a
non-Western tuning system
(ex.
Arabic music).
By following the
procedure below, you can
create
scales
which include "quarter-tones" (pitch intervals
equal to
about
1/2
of
a
semitone).
[What To Do]
First,
turn off the
power
for a
momen
t.
Then, while holding
down
the iTUNEl button, turn
power
on.
You
will
then be
in
the
mode
which allows
you
to use quarter-
tones.
Next,
while holding
down
iTUNEj
.
press
the
Tone button
(upper row; pink)
which corresponds to
the note
you wish to
have
set
to a quarter-tone (the pitch
will
be lowered by about
1/2 a
semitone).
Any number
of notes
among
the twelve
from
C through
B
can be
specified.
To
se
ta quar
ter-tone
back to the
normal
pitch,
keep holding
down
ITUNEl
and
press
the
Tone
button again
which
corresponds to the note
you
wish.
Once your
settings
have been made,
release
your
finger
from
the lTUNEj button.
The instrument
will
then be ready to
play.
As
long as
the
power
remains
on,
quarter-tone settings
can
be
made
at
any
time.
To
restore
the instrument's
standard tuning,
simply turn the
unit off
and then
on
again.
