Abstract
A drum pedal sensing system may include a base, a foot board, a pedestal, a beater, beater stem, and beater holder operatively connected to the foot board, a sensor holder, and a sensor fixedly coupled to the sensor holder. The beater holder may include a sensing surface that may rotate as the foot board is depressed and that may remain a substantially constant distance from the sensor as the sensing surface rotates. Additionally, the system may include a microprocessor operatively coupled to the sensor that receives signals from the sensor corresponding to motion of the sensing surface. Based on sensed changes such as changes in position, velocity, or acceleration, the microprocessor may determine whether the beater has contacted a drum face and, if so, may send an output signal to a stomp box, drum brain or similar element, with the amplitude of this output signal proportional to strength of the hit.
