The Main Types
of
MIDI
message Used by
the
R-8M
MIDI
uses
many
different
types of
MIDI
messages
to transmit a
wide
variety
of musical
information.
MIDI message
can be broadly divided
into
two
categories; data that
is
handled by
MIDI
channels
(channel messages), and data
that
is
handles without regard
to the
MIDI
channel (system messages).
Data handled by MIDI channels
(channel
messages)
These messages
transmit
perfomiance
nuances. Normally, these
messages
are
all
you
will be
using.
The
settings
of the sound source
will
detemnine the
effect that
these
MIDI
messages
will
have.
Note
message
This message
transmits the
drum
hits
(corresponding
to
the notes pressed
on
a keyboard).
Note
messages
include the following.
Note number The
type of
drum
sound
(a
number
indicating the
key
position)
Note on
Strike the
drum
(press the key)
Note
off
Release the key
Velocity
Note on the strength with which the
drum
(key)
is hit
Note
off
Key
release
strength
(when
using a keyboard that transmits note
off
velocity)
Note number
is
expressed
as
a number from
—
127, with middle
C
(C4) as 60. In general, the note
number
determines
the pitch.
However,
for riiythm
sound sources, the note
number
is
used
to specify
the type of
drum
sound.
The R-8M's
Instrument Section allows
it
to
be
used as
a conventional rhythm
sound
source, and the Performance
Sections allow
it
to be played
like
a synthesizer
sound
source with
different pilches for each note number.
* Most
rhythm machines
either transmit the "note
on" and
"note
ofT
messages
in
immediate
succession, or transmit the note
off
message
at
a
specific
time
inten/al after
the note on
message.
Pitch
bender message
This
message
transmits changes
in
the
bender
lever position
(pitch).
AftertOUCh
message
This message
transmits changes
in
aftertouch (the force with which you
press
down on
the
keyboard
to
modify the sound). This message
is
ignored by
the
R-8M.
Program change message
This message
is
usually
used
to select
sounds, and includes a program
number
(1
—
1
28) that specifies
the
sound
to
be
selected.
When
the
R
-
8M
receives this
message
it
will select
Patches or Feel Patches.
The
program change
map
(
cr page
57) allows you
to freely specify the
Patch and/or Feel Patch
that
will
be
selected
by each incoming program number.
Control
change message
This
message
includes messages such
as
modulation or pan
that
are used for musical expression.
A
control
number
is
used to distinguish the
various
functions.
Each
MIDI
device
will
respond
to this
message
in a different
way.
The
Instrument Section of
the
R-8M
can
receive control
numbers
to
modify
the
sound of
specified
instruments
in
up
to
9
different
ways (cr
page
33).
