To know the relationship between the sound generated by various drawbars it is necessary to divide the size in
feet of a given drawbar for the size of the first drawbar to the left (that generates the same sound of a 16' pipe).
The white drawbars are those whose relationship with 16' is a power of 2 (2, 4, 8 and 16), this means that these
drawbars have intervals of one or more octaves among them.The octave interval is considered the "purest",
and the white color indicates this interval. Registers that have intervals different from the octave are marked by
the black colour. An exception is made for the first two drawbars, as the first is not white even though it has an
interval of an octave, while the second seems to violate the harmonic scale (from low to high). These drawbars
are brown in color, as they are sub-harmonics of the 8' register, which is traditionally considered the root note.
Making an other comparisonn with an equalizer, drawbars can be used to generate sound according to
frequency; the first two drawbars on the left (16' and 5 1/3') control bass, the central group of four drawbars
(8', 4', 2 2/3 'and 2') define the main sound and the last three drawbars (1 3/5', 1 1/3' and 1') adjust the sound
brightness.
As in the most famous electromechanical organs, Legend and Legend Live feature 38 drawbars, divided into
five groups, called Sets. First two groups on the left, called UPPER A and UPPER B, are the drawbars
dedicated to the upper manual. The two sets on the right, LOWER A and LOWER B, are the drawbars of the
lower manual. The central group is made up of the two pedalboard drawbars.
To use the drawbars of Set A, press the key A# of the Black Octave for each manual (
Legend ) or the button
[DRAWBARS SET A] (
Legend Live ). To use the drawbars of Set B, press the key B of the Black Octave
(
Legend ) or the [DRAWBARS SET B] button ( Legend Live ). The pedalboard drawbars are always active. The
led on the Black Octave key (
Legend ) or the button [DRAWBARS SET] ( Legend Live ) show which Set is
currently in use.
