Adding Click And Background Noise - Viscount DB-5 Operating Manual

In this video page, you can regulate the operating mode of the bass section. The
BassMode
parameter allows you to play the bass, in monophonic mode, on the lower manual together
with the LOWER manual Drawbars, by setting it as . If this parameter is changed to
Layer
the bass will be played with the BASS section Drawbars only, in polyphonic
Replace
mode. Finally, if is selected the BASS section will be played with the optional
Pedal
pedalboard, in polyphonic mode. If the OB5 does not detect a pedalboard connected to the
rear, the display will show:
The video page described previously also contains the (Sustain) parameter, which

4.10 ADDING THE CLICK AND BACKGROUND NOISE
The original electromagnetic organs had a distinctive "click" produced by a flawed electronic
circuit which produced abnormal amplification of the voltage received from the Drawbar
buses, and a background noise generated both by the note leakage due to rotation of the
tone wheels (91 toothed wheels, which generated an electrical voltage varying depending
on their number of teeth, used to produce the sound, and 5 smooth wheels for mechanical
balancing of the rotation system), and by the internal motor used to rotate the wheels
themselves.
