The Organ
Drawbars
Galileo’s upper and lower manuals each have nine dedicated drawbars labeled UP
and LOW. The pedal manual has two drawbars labeled PDL.
The drawbars are used to configure the basic signal produced by the organ. They
work in a form of additive synthesis. As a drawbar is pulled, the amount of the
corresponding signal in the mix is increased. The numbers above each drawbar
represent the conventional labeling used on most electro-‐magnetic organs and are
borrowed from pipe lengths found in pneumatic organs.
Below is a list of drawbars and corresponding tones:
