Percussion - Hammond A-3 Playing Manual

An important component of the Hammond Sound is "Touch-Response Percussion Control™."
The Percussion controls on the XK-5 consist of four separate tabs, located immediately to the right of the Drawbars, which control har-
monic Percussion tones playable from the Upper Manual. They control all the same functions as the tilt tablets on a tone-wheel Ham-
mond.
[ON] tab
This tab, when "ON" (LED lit), turns the Percussion effect "ON." The Percussion tone will sound in accordance with the settings for the
other three Percussion controls.
NOTE: In the "ON" position, all of the Upper Manual Drawbars will be effective except the 1' (fourth white) Drawbar. This duplicates
the performance of a tone-wheel organ. In the "OFF" position, the 1' Drawbar is effective as usual. However, you can change this
parameter if you wish. See the next page for more information on how to do this.
[SOFT] tab
This tab regulates the volume of the Percussion tone. When it is "OFF" (LED not lit), the Percussion effect will be very prominent. It will
also be noticed that the tones from the Drawbars are reduced in volume to compensate for the addition of the Percussion tones. When
this tab is "ON" (LED lit), the Percussion effect is much less prominent. The volume of the Drawbar tones remains unaffected by the
addition of the Soft Percussion effect.
[FAST] Touch Tab
When this tab is "OFF" (LED not lit) the Percussion tone will decay slowly like a bell. When it is "ON" (LED is lit) the Percussion tone
will decay rapidly like a xylophone.
[THIRD] tab
This tab determines the pitch at which the Percussion tone sounds. When set at "SECOND" (LED not lit), the pitch is up one octave
with respect to the Fundamental (8') Drawbar; when set at "THIRD" the Percussion pitch is up an octave and a fifth with respect to the
Fundamental Drawbar.
NOTE: You can adjust the parameters of the Percussion to your liking. See the next page for more information on how to do this.
NOTE: As on a tone-wheel organ, the Percussion tones are normally available only with the second group of Upper Manual Drawbars.
Thus the "B" Preset Key must be active to obtain Percussion. However, you can set the Percussion so that it is available on every Pre-
set Key if you wish. See page 104, "PATCH LOAD PARAMETERS," for more information on how to do this.

USING PERCUSSION
When Percussion is used, the sound of the 1´ Draw-
bar is canceled just as on a typical tone-wheel or-
gan. Therefore, a common registration technique
used by jazz organists is to keep the 1' Drawbar
out all the way, and turn the Percussion "ON" AND
"OFF" while playing for a dramatic and easy change
in sound.
