MIDI INFORMATIONS

What is MIDI

The MIDI (

usical

nstrument

igital

nterface) allows instruments of different makes and types to communicate with

each other by means of this clearly specified protocol of codes. This makes it possible to create systems of MIDI
instruments which offer much better versatility and control than can be achieved with separate instruments. To make
this communication possible, all MIDI instruments are equipped with two or three 5 pin DIN connectors marked:
-

MIDI IN

By means of this connector, the device receives the MIDI data emitted by other units.

MIDI OUT

By means of this connector, the device sends the MIDI data it has generated to other units.

MIDI THRU

This connector, used to connect several units in series, emits the MIDI data exactly as they
are received by the respective MIDI IN port.

N.B.:

Legend ‘70s is not equipped with the MIDI THRU connector.

However, a Thru software function is available.

For example, most instruments equipped with MIDI interface transmit MIDI messages which specify which note has
been played and with what velocity by means of the MIDI OUT connector. If this connector is connected to the MIDI
IN of another MIDI instrument, such as a synthesiser or an expander, the connected instrument will give a precise
response to the notes played on the transmitter instrument. This allows you actually to play two instruments at the
same time, and obtain special multi-instrument sounds. The same type of transfer of information is used to record
MIDI sequences. A sequencer can be used to record the MIDI data transmitted by the

Legend ‘70s

. When these

recorded data are sent to the

Legend ‘70s

, it will automatically play back the recorded performance.

MIDI Channels

The MIDI is able to transmit a multitude of digital data by means of a single cable and thus a single connector,
thanks to the MIDI channels. There are 16 MIDI channels, so MIDI messages are processed when the channels
of the receiver and transmitter instruments are the same.

Legend ‘70s

transmits and receives MIDI data in the

channel setted with the

Global Channel

parameter in the

SYSTEM / MIDI SETTINGS

section.

Main MIDI messages transmitted and received by the Legend

‘70s

CHANNEL MESSAGES

NOTE ON

This message is transmitted when a keyboard note is pressed. Each Note On contains the following data:

Note On

: when the key has been pressed;

Note Number

: which key and therefore note has been pressed;

Velocity

: dynamic, that is, the quantity of pressure on the key.

Note numbers vary between 0 and 127; the central C corresponds to number 60.

Data format:

9nH kkH vvH

n=channel number:

00H – 0FH (1 – 16)

kk=note number:

00H – 7FH (0 – 127)

vv=note on velocity:

01H – 7FH (1 – 127)
00H (0) Note Off

NOTE OFF

This message is transmitted when a key is released. When the message is received, the corresponding sound
stops. A Note Off message contains the following data:

Note Off

: a key has been released;

Note Number

: which key has been released;

Velocity

: dynamic, that is, energy of the release.

Data format:

8nH kkH vvH
9nH kkH 00H

n=channel number:

00H - 0FH (1 – 16)

kk=note number:

00H – 7FH (0 – 127)
