CHAPTER
IV:
REFERENCE
SYSTEM
MESSAGES
System messages
include Exclusive messages,
messages used
for
synchronizing
the
performance
of multiple
units,
and
other
messages
employed
for
diagnostic purposes.
The SDE-330
supports
the
use
of Exclusive
messages.
•
Exclusive
Messages
Exclusive
messages handle
information
related to a
unit's
own
unique
sounds, or other device-
specific
information. Generally,
such messages can only
be exchanged between
devices
of the
same model by
the
same
manufacturer.
Exclusive
messages can be
employed
to
save
the
settings for Effects
Programs
into
a
sequencer,
or
for
transferring
such
data
to
another
SDE-330.
Whenever
Exclusive
messages
are
to
be used
for
communication,
both devices
must be
set
to
the
same
Unit
Number.
On
the
SDE-330,
the
Unit
Number
is
the
same
as
the
MIDI
channel
number.
MIDI
Implementation Chart
MIDI
has
made
it
possible
for
a
wide
range
of musical instruments
to
communicate
with
each
other,
but
that
doesn't
necessarily
mean
that
the
many
types of data
will
all
be
understood.
If
communication
between two connected
MIDI
devices
is
to
be
successful,
it
must
take
place using only
the types of data
that
they
have
in
common.
It
is
for this
reason
that
every owner's
manual
—
for
all
kinds of
MIDI
devices
—
always
includes a
MIDI
Implementation
Chart
as a
quick
reference
to
the types of
MIDI
messages
it
is
capable
of handling.
You
should
compare
the
MIDI
Implementation
Charts
for
any
two
devices
in
order
to find
out
which
types of
data
can be exchanged.
Since these
charts are standardized,
you can
place
them
so
they
overlap. This
way
you can
easily
compare
the receiving
device with
the transmitting device.

*For
detained
information
on
MIDI
data
of
the
SDE-330,
a separate
"MIDI
Implementation
document"
is
available
at
any Roland
Service
Station.
