Using Midi - Roland JX-1 Owner's Manual

Using
MIDI 2
in
addition to using
MIDI channel
to
transfer
performance
data
between
instru-
ments, there are
also
other types of data
that can
be
carried
by
MIDI.
These
include
Information concerned with
a specific unit's
sounds
or functions (system exclusive
data),
and
other data used
for
system monitoring.

t"-
Information
concerned with
a unit's
own
unique sounds
or functions
is
exchanged
as
System
Exclusive
Messages. System
Exclusive
Messages can only
be exchanged between
identical units.
Thus,
if
the
JX-1
sends System
Exclusive
Messages, they have
meaning andareeffectiveonly
if
received
by another
JX-1.
System
Exclusive
Messages
can,
however, be recorded
into
and
be played back by
a
sequencer.
O
The
JX-1
understands
and
uses
the
following three types of System
Exclusive
Messages;
•
Tone
Dump
Provides for the transfer of
all
data
for Edit
Parameters
for
the
currently selected Tone.
When
the
unit receives a
Tone
Dump,
all
Edit
Parameters
for
the current
tone
will
be altered
with incoming
data.
•
Bulk
Dump
Provides for the transfer
(in
bulk)
of
all
settings for
all
32
Memory
Tones.
Be aware, however, that
when
the
unit
receives a Bulk
Dump,
all
settings
previously
stored
in
the unit are replaced.
•
Parameter
Dump
After turning the System
Exclusive
switch
"ON," the data
for
each
Edit
Parameter
will
be output over
MIDI according to the operations
you perform using the buttons
and
sliders.
When
the unit receives
Parameter
Dumps,
its
settings will
be
altered to
conform with the
in-
coming
data.
The
result
will
be
the
same
as
if
the panel
controls
had
been used to manually
make
the
changes.
O
System
Exclusive
Messages Are
Transmitted/Received

down,
the
indicator
on
the "SYS EX" button
will
be
lit,
indicating that
the

System
Exclusive

(whether from
a
sequencer or
another
JX-1) will
be
recognized.

Other
Tyjpescif
fMtm
This unit also
recognizes the following types of data
(refer
to
"MIDI Implementation"
page
16):
Local
ON/OFF
(Reception Only)
If
you wish
to switch Local
"On" and
"Off",
do
so using
MIDI messages from
a sequencer.
Refer to the sequencer
manual
for details
on
how
to
do
this.
Note,
however,
that the unit
will
automatically be
set
to
Local
"ON"
each
time the unit
is
turned
on.
Active Sensing
This
type of data
is
used to monitor the
integ-
rity
of
the MIDI connectors
and
cables.
It
pro-
vides for
measures
to
be taken (such as cutting
off
all
notes)
when
abnormalities are detected.
