Abstract: An electronic high-hat circuitry system allows the drummer to manually choose the sounds that an electronic high-hat makes when the drummer's foot is off of the pedal and the high-hat instrument is struck. When the pedal is at or near the top of its travel, a primary circuitry switch disables normal foot-controlled positioning circuitry and enables a secondary circuit that sends a manually selected positioning signal to a drum module. When the pedal is again pressed down, the primary circuitry switch returns control to the primary, pedal controlled circuit. An optional tertiary circuit allows for the choosing of a different sound when the secondary circuit is activated and the high-hat cymbal is tilted, and is used primarily for accent notes. A control panel is used by the drummer to select the desired high-hat sounds of the secondary and tertiary circuits.
