Omni
As
mentioned
earlier,
itis
necessary
for
the
channel
of
the
slave
device
to
match
the
channel
of
the
master
device
in
order
for
MIDI
messages
io
be
received.
However,
there
is
one
exception
which
you
should
know
about;
Omni
on/
off.
Omni
on:
Messages
of
all
channels
will
be
received.
Messages
of
the
specified
channel
will
be
received.
Omni off:
MIDI IN
Channel 5
(Omni on)
Slave
MID! OUT
Channel 4
if
you
set
the
slave
device
to
Omni
on,
it
will
receive
MIDI
messages
regardless
of
the
MIDI
channel
on
which
the
master
device
transmits.
However,
when
using
asequencer
to
create
a
MIDI
ensemble,
you
must
turn
Omni
off
if
you
want
each
part
to
be
played
independently.
Since
most
MIDI
instruments
are
able
to
make
effective
use
of
MIDI
channels,
you
will
normally
leave
them
set
to
Omni
off.
To
select
Omni
ON
for
the
FP-8,
refer
to
page
18.
Program
Change
Messages
Program
Change
messages
are
MIDI
messages
that
select
sounds.
Actually,
these
messages
tell
the
receiving
device
to
“switch
to
sound
number
X”;
not
to
“switch
to
a
pianosound”
(for
example).
The
sounds
of
MiDl
instruments
are
numbered
from
1
to
128
(these
are
referred
to
as
program
numbers),
and
when
a
program
change
mes-
sage
is
received,
the
sound
of
the
corresponding
program
number
is
selected.
This
means
that
even
for
the
same
program
number,
different
instruments
and
sound
mod-
ules
will
produce
different
sounds.
Make
sure
you
know
the
relationship
between
the
program
numbers
and
the
sounds
of
the
slave
device
before
you
transmit
program
change
messages.
To
select
Program
Change
numbers
for
transmission,
refer
to
page
18.
;
Control
Change
Messages
These
messages
enhance
musical
expressiveness,
for
example,
by
turning
the
Chorus
effect
on/off
or
adjusting
the
volume.
Control
change
messages
can
be
divided
into
those
that
simply
say
“turn
effect
XYZ
on/off”,
and
those
that
say
“set
effect
XYZ
to
a
setting
of
ABC”.
MIDI messages used by the FP-8
Note messages ... are transmitted when you press a key;
“play
such
a
note,
at
such
a
volume,
until
such
a
time”.
Program

with

(page

...
“activate
the

ef-
fect”
is
transmitted
when
you
press
the
damper
pedal.
“Activate

is
transmitted
when
you
press
the
soft
pedal.
“Activate
the
sostenuto
effect”
is
transmitted
when
you
press
the
sostenuto
pedal.
“Turn
Chorus
or

is
transmitted
when
you
press
CHORUS
or
REVERB.
“Adjust

is
transmitted
when
you
move
the
MONITOR

siider.
When
these
MID!
messages
are
received,
the
FP-8
will
take
the
appropriate
action
by
playing
a
note
or
controlling
an
effeci.
As
a
group,
these.
messages
are
known
as
Channel
messages,
and
are
handled
independently
for
each
MIDI
channel.
In
addition
to
these,
MIDI
includes
messages
that
are
handled
not
by
a
channel,
but
by
the
entire
system;
System
messages
(for
example,
System
Ex-
clusive
messages).
System
Exclusive
Messages
It
was
mentioned
earlier
that
MIDI
is
a
world-wide
stand-
ard,
but
Exclusive
messages
are
the
exception.
Exclusive
messages
are
unique
to
each
manufacturer.
Unlike
the
general-purpose
messages
we
have
been
describing,
these
messages
are
used
to
exchange
information
that
is
unique
to
specific
manufacturers
and/or
devices.
MIDI
Implementation
Chart
MIDI
has
made
it
possible
for
a
wide
variety
of
devices
to
exchange
information,
but
it
is
not
always
true
that
all
types
of
MIDI
messages
can
be
exchanged
between
all
types
of
devices.
For
example,
if
you
use
a
synthesizer
as
a
master
device
to
control
a
digital
piano,
the
pitch
bender
(the
lever
or
wheel
that
modifies
the
pitch)
of
the
synthe-
sizer
will
have
no
effect
on
the
sound
of
the
piano.
The
important
thing
to
keep
in
mind
when
using
MIDI
is
thatthe
slave
device
must
be
able
to
‘understand’
what
the
master
is
‘saying’.
in
other
words,
the
MIDI
messages
musi
be
common
to
both
master
and
slave.
