What Midi Is - Viscount Cantorum Duo Plus Reference Manual

Double wing
The tallest pipes are placed in the centre. As the pitch lowers, the pipes are gradually
distributed further and further to the outside, alternating.
Single wing (left)
The tallest pipes are placed to the left, and the smaller (with higher pitch) pipes to the right.
Single wing (right)
This pipe configuration is the opposite of the previous one: the lowest pitched pipes are
placed on the right and the highest pitched ones to the left.
Center
All the pipes are placed in the central position inside the wind chest, so the sound is not
affected by the position of the pipes.
Alternated
The pipes are placed alternating in two positions (e.g. C in one position, C# in the other).

What MIDI is

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: The connector through which the instrument receives the MIDI data transmitted by other units.
- MIDI OUT: The connector through which the instrument sends the MIDI data it has generated to other units.
- MIDI THRU: This connector, not always provided on all instruments, is used for connecting several units in
series, since it transmits the MIDI data exactly as they are received by the respective MIDI IN port.
Most instruments equipped with MIDI interface transmit MIDI messages which specify, for example, 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.
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.
