Abstract: An electronic drum with active crosstalk detection includes a first vibration transducer configured to generate a first signal in response to a strike to the electronic drum, and a second vibration transducer configured to generate a second signal in response to vibrations in a mount coupled to the electronic drum. A circuit compares an amplitude of the first signal and an amplitude of the second signal within a predetermined time, and determines whether the signal was generated by crosstalk or an actual drum hit based on various criteria.

The trigger data includes a strike velocity of a drum-pad zone on a drum pad. The method includes displaying an image of a drum associated with the drum pad on a display, displaying a first portion of the drum in a first color, and changing the first portion of the drum to a second color. The second color is determined by a magnitude of the strike velocity.

Abstract: Electronic percussion instruments with enhanced playing areas and methods and systems for generating electrical signals in response to impacts to a playing surface are disclosed. A semi-permeable playing surface covering an acoustic noise reducing cavity of an electronic percussion instrument may receive an impact within a predefined impact region, and an electrical signal may be generated in response by an electromechanical sensor that senses the impact. In many instances, the generated electrical signal may be configured to be equivalent in magnitude to any other electrical signal generated by the electromechanical sensor, in response to any other received impact within the same predefined impact region.
