The present invention includes a method and apparatus for temporary dampening and temporary conversion of a wide range of an analog percussion surfaces into electronic percussive surfaces by means of a modular self-dampening trigger system attachable in an openly modular configuration to the underside of said analog percussive surfaces in a manner that allows physical variations to traverse different media and span distance and time and allowing for discrete detection and manipulation of said variations. A trigger system that is releasably attachable to an acoustic percussion element has a metal cover plate releasably affixable to an undersurface of the acoustic percussion element, the metal cover plate partially covering less than half of the undersurface. A plurality of piezo sensors are releasably affixable to the undersurface of the acoustic percussion element. A rubber dampening element with a footprint substantially similar to a footprint of the metal cover plate is formed from a flexible thin sheet of rubber with an opening corresponding to and aligned with each of the piezo sensors, the openings each sized slightly larger than the piezo sensor. The rubber dampening element is sandwiched between the undersurface of the cymbal and the metal cover plate.
