An
important
feature of
MIDI
is
that
it
uses a
number
of
different channels.
Performance data
can be
transferred
between two
instruments only
when
the channel on
the receiving unit matches
the channel
on
the
transmitting
unit.
For
example,
if
the
transmitting unit
is
using
channel
1,
only an
instrument
set to receive
on
channel
1
would
re-
spond
to
the incoming
data.

When
recording
on
a
sequencer,
a
number
of
diffe-
rent
channels can be used. This allows different
sound modules
(or individual sounds) to
be
played
separately
(as
needed).

On
the
JX-1
,
you
select
one
channel
on which
both
transmission and
reception
will
take
place.
The
manner
in
which you
select
this
channel
is
explained
in
"Performance
Functions,"
page

O
MIDI Data Types
on
the
JX-1
The types of MIDI data that are recognized
(when MIDI channels match) by the
JX-1
are
as
follows:
•
Performance Data Produced by
a
Keyboard
Note
Numbers and
their Velocity are
produced
when
keys are played.
Velocity
when
key
is
released
is
only transmitted.
•
Pitch
Bend Data
Information regarding
pitch
bend
is
produced
when
the
bender
lever
is
moved. Bend range
can
be
set
on the
receiving instrument.
•
Control
Change
Data
Modulation Depth produced
by the
bender
lever;
and whether
the Hold pedal
is
depressed
or
not
(ON
or OFF).
Volume
information
is
dealt with only
when
re-
ceived.
•
Program Change
Data
These
cover the
selection
of
sounds
using the
Tone
buttons.
The Sub Tone
for the Dual func-
tion
is
also
handled.
Refer to
"Sound and Corresponding Program
Change Numbers" page

About MIDI Implementation Chart
MIDI
makes
it
possible for
an extensive range of
information
about
a
performance
to
be com-
municated.
However, depending on
the par-
ticular
devices
you have connected, the types of
data that can
be communicated can vary con-
siderably.
You
should
refer
to the MIDI Im-
plementation
Charts supplied
with the devices
you
are connecting
in
order to confirm
what
types of
MIDI messages can be sent
out
and/or
received (see below).
When
comparing
charts,
if
"O" appears
for a particular
type of
message
on both
charts,
communication
will
be
successful.
