MIDI
Parameters
The
following
parameters
must
be
set,
in
order
to
carry
out
the
various
MIDI
control
operations
that
we've
just
discussed.
1.
RECEIVE
CHANNEL
(1
through
16)
MID!
information
is
transmitted
on
16
channels,
and
for
key
number
reception,
the
RX21
must
be
set
to
the
same
MIDI
channel
as
the
MIDI
instrument(s)
to
which
it
is
connected.
The
sequencer
or
music
computer
used
to
transmit
the
MIDI
data
might,
for
example,
be
transmitting
melody
data
to
a
synthesizer
on
channel
1,
and
rhythm
data
to
the
RX21
on
channel
2.
The
RX21
must
therefore
be
set
to
receive
on
channel
2,
to
prevent
the
melody
data
from
triggering
the
rhythm
machine.
To
set
the
channel
number,
press
the
MIDI
button
twice.
"RECEIVE
CH-cc"
will
appear
on
the
LCD
("cc"
being
the
channel
number).
To
change
the
channel
number,
press
the
1/YES
button
to
increase
the
number
and
—1/NO
button
to
decrease
it.
To
exit
this
mode,
press
any
main
function
key.
The
MIDI
Receive
Channel
that
you
have
selected
will
remain
even
after
the
RX21
power
is
turned
off.

CHANNEL
INFORMATION
AVAILABLE
In
this
mode,
the
RX21
receives
MIDI
key
number
data
from
an
external
source,
as
described
in
KEY
NUMBER
RECEPTION
at
the
beginning
of
this
chapter.
A
key
number
corresponds
to
the
number
(pitch)
of
a
key
played
on
a
synthesizer
key-
board.
Middle
C,
for
example,
is
MIDI
key
number
60.
A
MIDI
sequencer,
for
ex-
ample,
outputs
key
numbers
to
a
keyboard,
causing
the
synthesizer
to
play
the
corresponding
notes.
The
RX21
has
9
different
instrument
sounds.
Each
of
these
has
been
assigned
a
MIDI
key
number
between
45
(A2)
and
60
(C3,
or
MIDDLE
C).
These
are
as
follows:
