Button Explanation
Lit (ON)
The percussion sound will disappear slowly. The percussion
will have a more gentle attack.
Dark (OFF)
The percussion sound will disappear quickly. The percussion
will have a sharper attack.

Percussion on a tone wheel organ (Single Trigger Algorithm)
The percussion on tone wheel organs did not apply to all notes that were
played. It was applied only to notes which were played simultaneously
from a condition where no notes were being played. When notes were
played legato (smoothly and connectedly), percussion was applied only to
the first-played note. When notes were played staccato (articulating each
note separately), percussion was applied to all notes. This method is
referred to as single trigger algorithm, and is a very important element in
organ performance. On tone wheel organs, percussion was produced by an
analog circuit. For this reason, when there was only a very short time
interval from when one key was released until the next key was pressed, the
percussion circuit was unable to recharge fully, causing the percussion to
sound at a lower volume. The VR-760 simulates this behavior, and also
allows you to modify the organ voice settings to adjust the recharge time
characteristics of the circuit (p. 71).
