MIDI
messages
used
by
the
G-800
The
way
a
device
responds
when
it
receives
MIDI
messages
(i.e.
how
it
produces
sound,
etc.)
depends
on
the
specifications
of
that
device.
This
means
that
if
the
receiving
device
is
not
able
to
perform
the
function
specified
by
the
incoming
message,
the
musical
result
will
not
be
what
you
expected.
What
it
comes
down
to
is
this:
there
are
several
levels
of
MIDI
compati-
bility,
and
not
all
MIDI
compatible
instruments
understand
(i.e.
receive)
all
existing
MIDI
messages.
Note:
MIDI
messages
for
which
reception
capability
is
required
by
the
GM
system
(level
1)
are
marked
by
a
*
sign.
Note messages *
These
messages
convey
notes
played
on
the
keyboard.
They
include
the
following
informa-
tion:
Note
number
A
number
describing
the
note
corresponding
to
the
key
you
pressed
or
released.
Note-on
A
messages
signalling
that
you
pressed
a
key
(i.e.
“start
playing
now").
Note-off
|
A
message
signalling
that
a
key
was
released.
Velocity
A
value
describing
how
strongly
you
pressed
a
key.
Note:
On
many
instruments
(such
as
your
G-800),
a
note-on
message
with
the
velocity
value
“0”
is
used
to
signal
the
end
of
a
note
(i.e.
velocity
value
“0”
effectively
functions
as
note-off
mes-
sage).

On

By
using
Bank

(which
are
a
type
of
control

message),
an
even

variety
of

can
be

were
added
when
it
became
clear
that
the
maximum

(128)
was
no
longer
sufficient
to
access
all

of
a

Note:
Do
not
forget
to
send
a

does
nothing
whatsoever.
