are

when

MIDI
channel
matches
that of the

if
the
MIDI
channels
are set
as
follows,
only

MIDI
messages
used
on
the
R-8MK
I!
There
are
a
variety
of
MIDI
messages, each
carrying
different
types
of
information.
MIDI
messages
are
divided
Into
two
categories
:
'Channel
messages'
that
are dealt
with
in
each
individual
MIDI channel,
and
'System
messages'
which
are dealt
with
r^^ardless of the
MIDI
channel
setting.
< Channel
Messages >
These messages
are
used mainly
for transmitting
performance
information.
Normally,
you can
control
almost
everything
using
Channel messages.
How
each MIDI
message
controls the
system
varies
depending
on
the
setting
on
the
receiving device.

Note
Messages
Note messages
are for playing
sounds and
carry
the following information
:
Note
Number
:The
pitch
of
a
sound
(the
number
that represents
the
position
on
the keyboard).
Note
On
:Pressing
a
key
(or
key pad
in
this
case).
Note
Off
:Releasing
a
key.
Velocity
:The strength
with
which
a
key pad
is
played.
*The
notes
on
a
MIDI keyboard
are
represented by the
numbers
to 127.
Middle
C
(C4)
is
obtained
by
playing
Note
Number
60.
*
R
-
8MK
i i
does
not
send Note
Off
messages
immediately
after
a
Key
Pad
is
hit.
There
is
a
short
interval
after
which
Note Off
messages
are
sent.
*ThB
R-8MKII
has been
set
so that the
sound
will
not be cut
even
when
it
receives
a
Note
Off message. This
is
because
all
the
internal
Instruments
will
naturally
decay
even without
receiving
a
Note
Off.
However,
if
you wish
to
use the R
-
8MKII
as
a
sound module
for
a
keyboard,
you
may
wish
to
mute
a
sound
when
releasing
a
key.
If
so,
turn
on
the
Note
Off Switch.
