Utility - Viscount DB-5 Operating Manual

N.B.: PIN 11 senses connection of a connector to the ROTARY TONE CABINET jack. If the voltage is not
inside a range from 18 to 30 V DC, the tone cabinet might not work correctly. Moreover, sudden current
surges might cause malfunctions or breakdowns of the OB5 or of the tone cabinet.
You can use the [ROTARY ON/OFF] switch on the panel on the left of the manuals to
switch the cabinet motor on or off, while the [ROTARY SLOW/FAST] is used to select the
rotation speed (fast/slow) of the tone cabinet motor.

7. UTILITY

The OB5 offers a number of utility functions, such as tuning of the instrument, the display
contrast, MIDI and the assignment of functions to the foot-switches which can be connected
to the rear panels to optimise use of the organ.
When the [UTILITY] button is pressed, the display will show the main page containing all
the utility functions:
Now let's take a detailed look at these functions.
7.1 MIDI
The MIDI (Musical Instrument Digital Interface) 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:
For example, most instruments equipped with MIDI interface transmit MIDI messages
which specify which note has been played and with what dynamics 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.
- MIDI IN: By means of this jack, the device receives the
MIDI data emitted by other units.
- MIDI OUT: By means of this jack the device sends the
MIDI data it has generated to other units.
- MIDI THRU: This jack, used to connect several units
in series, emits the MIDI data exactly as they are
received by the respective MIDI IN port.
