9. MIDI
The letters MIDI stand for the Musicai Instrument digital Interface, an international standard for connecting synthesizers,
drum machines, and other electric/electronic musical instruments so that they can exchange keyboard and program data.
Through this interface, the organist can play a variety of instruments from a single instrument. (The extract types of data
that may be exchanged and the functions that may be controlled vary with the instruments connected through this
interface.)
9.1 Introduction
@ Connectors
Instruments with the MIDI interface feature the follow-
ing three receptacles which accept the DIN plugs on
MIDI cables.
IN Accepts the incoming keyboard, program, and
other types of data.
OUT Transmits keyboard, program, and other types
of data.
THRU Passes the data received on to another instru-
ment.
H Connections
The MIDI interface allows electric/electronic musical
instruments to exchange keyboard, program, and other
types of data. The instruments can be connected so that
the data flows only one way — with only one instrument
transmitting and the other(s) receiving — or so that data
flows both ways. The organist specifies the data path-
ways by connecting the MIDI OUT terminal of the
transmitting instrument to the MIDE IN terminal of the
receiving one.

The data received may also be retransmitted to other
instruments through the MIDI THRU terminal.

@ Channels
Since the MIDI interface can connect several instru-
ments at once, the organist needs a way to specify
which instrument is to play. This is done by assigning
channel numbers, numbers between 1 and 16, to the
instruments.
i Features
The MIDI interface on the SR Series of organs transmits
the following types of data.
(a) Keyboard data
By connecting the organ to a synthesizer, the organist
can play the organ from the synthesizer keyboard and
vice versa.
(b) Channel specifications
The organ always assigns the following MIDI chan-
nels to the keyboard,
Ch. 1. UPPER
Ch. 2. LOWER
Ch. 3. PEDAL
Ch. 4. SOLO (Not available on the SR5)
The registration memory section can receive on any
MIDi channel between 1 and 16.
{c) Program change
The organist can send a command from the organ to
a synthesizer to change the program number. (For
the procedure, see p.53.)
(d) Volume control
The organist can control the synthesizer volume from
the organ and vice versa.
(e) Clock signals
Signals from the organ can synchronize the drum
machine tempo and rhythm with those of the organ.
Other signals start and stop the drum accompani-
ment. (For the procedure, see p.55.)
