7. MIDI

7.1 GENERAL INTRODUCTION

MIDI stands for Musical Instrument Digital Interface.
This interface allows electronic instruments, even of different makes and types, to dialogue with each other or with a
computer, in order to exchange a large number of items of information by means of a clearly defined, detailed protocol of
codes. This allows different functions to be obtained from the connected machines, without necessarily having to touch them
at all.
Electronic musical instruments equipped with MIDI interface have one or more DIN 5 pin connectors which are the MIDI
connectors. There are normally three MIDI connectors, as follows:
- MIDI IN: Connector through which the machine receives the MIDI data emitted by other units
- MIDI OUT: Connector through which the machine emits the MIDI data it has generated
- MIDI THRU: Used for series connection of a number of receiver units, this connector emits the MIDI data exactly as they
are received by the MIDI IN port.
In the Prestige organ, these connectors are located in the connection panel on the left under the first manual.
Transmission and reception of MIDI data are subdivided into channels, so that given one transmitter unit, of all the receiver
units connected, only the one tuned to the transmitter channel will respond.
The MIDI protocol includes 16 channels, so given one transmitter instrument, separate control of up to 16 instruments
connected to it is possible. When the MIDI transmission channel is selected, we will connect only to the unit with the same
receiver channel.
Naturally, if two MIDI units are tuned to different channels they are unable to exchange data.

7.2 THE PRESTIGE MIDI IMPLEMENTATION

The Prestige organ is equipped with a MIDI interface which can be TRIPHONIC, meaning that every single manual is
able to transmit and receive on 3 indipendent MIDI channels, one a base channel and two auxiliary channels (A and
B).
MIDI selection keys
MIDI A channel of each section can be activated or disactivated through the register tabs indicated in the table.
The activation of MIDI BASE and MIDI B channels for each manual or for the pedal will be in operation through the
the control unit located in the drawer (see paragraphs 7.4 and 7.5).
The MIDI implementation of the Prestige allows also the transmission of Program Change messages (change of program
on the connected instrument), the adjustable MIDI Dynamic and the MIDI Filter function.
