A SHORT INTRODUCTION TO MIDI
The MIDI interface (Musical Instrument Digital Interface) allows instruments of different
makes and kinds to communicate with each other, using this very specific protocol of
codes.
This allows the creation of systems of MIDI instruments, offering much greater versatility
and control than is possible with single instruments.
To make this communication possible, all MIDI instruments have two or three 5-pin DIN
connectors called:
- MIDI IN:
- MIDI OUT:
- MIDI THRU:
Most instruments equipped with MIDI interface transmit MIDI messages which specify
which note has been played and with what dynamic by means of the MIDI OUT connector.
If this connector is connected to the MIDI IN connector of another MIDI instrument, such
as an expander, the second instrument will respond exactly to the notes played on the
transmitter instrument. This effectively enables you to play two instruments at once,
obtaining special multi-instrument sounds.
The same type of information transfer is used for recording MIDI sequences. A computer
or a sequencer can be used to record the MIDI data generated by the transmitter instrument.
If these recorded data are sent back to the instrument, it automatically repeats the recorded
performance.
NOTA
Always use top-quality cables for MIDI connections. In addition, we
recommend the use of cables no more than 5 metres long.
MIDI Channels
MIDI is able to transmit a multitude of digital data by means of just one cable, and thus just
one connector; this is thanks to the MIDI channels. There are 16 MIDI channels; therefore,
MIDI messages are processed when the channels of the receiver and transmitter devices
are the same.
The "Concerto" are able to transmit information on one or two MIDI channels simultaneously,
depending by the mode (Single, Dual or Split) selected.
In reception, the instrument can receive MIDI data on two MIDI channels simultaneously,
indipendently by the selected mode.
The connector through which the instrument receives the MIDI data
transmitted by other units.
The connector through which the instrument sends the MIDI data it
has generated to other units.
This connector, used for connecting several units in series, transmits
the MIDI data exactly as they are received by the respective MIDI IN
port.
