7.MIDI
MID!
(which
stands
for
"Musical
Instrument
Digital
Interface")
is
a
"universal
language"
adopted
by
most
musical
instrument
manufacturers
which
allows
MIDI
equipped
instruments
to
communicate
and
control
each
other,
regardless
of
what
company
they
are
made
by.
The
DW-6000
is
MIDI
equipped,
so
it
can
be
connected
to
other
MIDI
equipped
synthesizers,
sequencers,
rhythm
machines,
and
personal
computers.
HOW
MIDI
Works
(1)
The
MIDI
Control
System.
in
the
early
days
of
electronic
music,
it was
possible
to "in-
terface"
(ie,
interconnect)
older
monophonic
synthesizers
together
by using
two simple
voltage
signals.
One
was a
,''*^V
(control
voltage)
signal
tliat
determined
pitch.
The
•other
was
a trigger
signal
that
started
and
stopped
each
note.
But
such
techniques
are
too
cumbersome
and unreliable
for
today's
computerized
polyphonic
synthesizers.
So
the
MIDI
format
was
developed.
In
contrast
to
the older
CV/Gate
voltage
signals,
MIDI
uses
8-bit
digital
words
transmitted
serially from
instrument
to
instrument
to com-
municate
pitch,
note
on/off,
and
all kinds
of
information.

(2) MIDI
Jacks
and
Connections.
All
MIDI
jacks are
the same
physically
(using 5-pin
DIN
connectors).
However,
there are
three kinds
of MIDI jacks
according
to their
purpose
or
application.

•
MIDI IN: Receives MIDI
data.
•
MIDI
OUT: Sends MIDI
data.
• MIDI
THRU: Retransmits MIDI
data received
by
the MIDI IN jack
without any change. This is
used
to allow
2-4
instruments
to
work off
the same out-
put signal. (Some MIDI instruments
do not
have
MIDI
THRU jacks.)
