MIDI
MIDI
stands for
Musical
Instrument Digital
Interface, and is a
worldwide
standard for
transmitting notes, musical expressions, and oiher
musical data
between
electronic musical
instruments. If an
instrument
has MIDI, it can
transmit musical data to other instruments regardless
of the
manufacturer or
type.
When
a
note is played or a pcda! Is
pressed, this information
is
transmitted as a MIDI message.

How
MIDI message
is Transmitted
and Received
The
following is a simple explanation of
how
MIDI
message is transmitted and
received.
MIDI
Connectors The
following three connectors are used to transmit and
receive MIDI message. Use MIDI cables to
connect these
connectors as your setup requires.
MIDI IN :
This connector receives data from
another MIDI device.
MIDI
OUT : This connector
transmits
data
from the
device
itself.
MIDI THRU
: This connector
retransmits
the exact
data that was received at MIDI IN.
*Ygu can use
MIDI THRU to connect as many MIDI
devices as you like, but the practical
limit
is 4 or 5
devices.
If
more devices are connected, the
MIDI signal may
become
garbled, and the data may not be
correctly received.
MIDI
Channels
MIDI
uses a single MIDI cable to transmit
data independently to
two
or more MIDI
devices
using
various channels.
A MIDI
channel is similar to a
television
channel. By
changing the channel on a
television
set. you
can
view
programs from
many broadcast stations.
When
the
receiving channel matches the
transmitting channel, the data of
that channel will
be
received.
The
cable from the antenna carries television data
from
many
broadcast stations.

Set the
television
to
the channel of the
broadcast station
you v/ish to see.
MIDI uses sixteen channels (I —
16),
and when a MIDI
device is set to
receive
the same channel as
transmitted
by
the transmitting device, it will
receive that message. For the connections and MIDI
channel
settings shown in the
following
diagram, only
sound
module
B
will produce
sound
when the
keyboard is played.
