IS MIDI
The
R-8MK
II
can
be played using
an
external
MIDI
device, or
can
play
an
external
rhythm machine
or
MIDI module.
Also,
using MIDI
Exclusive
messages,
all
data
in
the
internal
memory
of the
R-8MK
li
can be
transferred to
an
external device.

MIDI
Message Communication
MIDI stands
for
Musical Instrument
Digital interface,
an
international
standard
for
communication between
musical instruments. MIDI compatible devices can
exchange
performance information (what notes were
played, for
how
long, at
what
volume,
etc.)
wrth other MIDI
devices,
even
if
they
are
of a
different
model
or
made
by
a
different
manufacturer.
Under
the MIDI standard,
performance
events
such
as
playing
on
a keyboard,
or depressing
a
pedal
are
handled
as MID! message.
MIDI
Connectors
MIDI
messages
are
transmitted
or received
(via
special
MIDI
cables)
through
the following MID!
connectors
:
MIDI
IN
:This
connector
receives
MIDI
messages
sent
from
an
external
MIDI
device.
MIDI
OUT
:The
R-8MK
II
sends MIDI messages through
this
connector.
MIDI
THRU
:An
exact
copy
of the
MID!
messages
received
from
MIDI
IN are sent
out
through
this
connector.
*
Using
MIDI
THRU
connectors,
it
is
theoretically
possible
to
connect
many
MIDI
devices.
However,
4-5
devices
seems
to
be the
practical
limit.
The more
devices
you connect
in
your system, the greater the
chance
of signal
delay or
deterioration.
MIDI
Channels
The
MIDI standard allows
for
the simultaneous transmission
of different MIDI
messages
to
several
MIDI
devices
through
one
MIDI
cable.
This
is
made
possible
by
the
use
of
MIDI channels. MIDI channels
are similar to
those
found on
a
TV.
By
changing
TV
channels,
you can watch programs
of
many
different
TV
stations.
That
is,
when
the
channel
of the
receiver
matches
that
of the
transmitter,
the corresponding channel
messages
are transferred.
TV
messages
from
various
TV
stations are
sent
through
the antenna's
cable.
