MIDI

About
MIDI
MIDI (Musical Instrument
Digital
Interface)
is
an
internationally
recognized standard
for
the
transfer
of
performance information
among
electronic
musical instruments
and computers.
The
majority of
contemporary electronic musical instruments are
equipped
to
support
this
standard.
Under
MIDI,
music
is
not handled
as
sound
itself.
Instead, perfor-
mance
information (and
whatever
commands
ac-
company
it)
are
converted
and
expressed
in digital
form.
All
such
digital
data
communicated through
MJDI
is
collectively
referred to as
"MIDI
Data."
Benefits of MIDI
By
using
MIDI to connect
your
JX-1 to
another
elec-
tronic musical
instrument,
you
can
then
use
it
to
control
the other
unit,
or
in
reverse,
the other
unit
can
be
used to control
your
JX-1
.
Whenever
you
play
your
JX-1,
MIDI data
describing v^hat
you play
(or
how
you use the
controls) will
automatically
be
transmitted.
On
the other hand,
whenever
the
unit
receives
such
performance
data,
it
will
play
notes,
and
otherwise be controlled
by the incoming
data.
In
addition,
this
performance data can
be
recorded
into a
sequencer (MIDI data recorder) while
you
play,
and then be played
back.
MIDI
IN
MIDI data
is
received here.
Use the MIDI
IN
connector to receive
data from
a key-
board
(or
other device)
you
are using to control
the
JX-1
.
A
MIDI cable
should be
con-
nected
so
it
runs
from here to the MIDI
OUT
on
the
external unit.

MIDI
OUT
MIDI data
is
sent
out from
here.
Use
it
to
send data to play
a
sound module, or to
be
recorded
in
a sequencer.
A

so
it
runs
from here to

THRU
This
connector
re-transmits
an
exact
copy
of
all
MIDI data arriving at
MIDI
IN.
The
MIDI data produced by the
unit
itself
is
NOT
sent
from
this
connector.
MIDI
THRU
is
useful for
chaining instruments together, such
as
when
a
keyboard controller or
sequencer
is
being used to
play
the
JX-1,
and
also
to pass
on
the data to another
sound generating
unit.
A
MIDI cable should
be connected
so
it
runs
from here to the
MIDI
IN
on an
external
unit.
