Electronic percussion synthesizer assembly
First Claim
1. In an electronic percussion synthesizer assembly of the type comprising a drum control unit;
- at least one drum head comprising a substantially rigid material having an upper surface and incorporating a transducer for converting mechanical movement of said upper surface to an electrical signal indicative thereof, said transducer being electrically connected to said control unit; and
a drum support member for supporting said drum head;
the improvement comprising;
a spider assembly for said drum head comprising a plurality of legs joined at one end for defining a hub, said legs comprising a resilient, flexible material and extending radially outward from said hub in spaced relation from each other, the free ends of said legs being secured to the perimeter of the underside of said drum head for supporting same; and
means for securing said spider assembly to said drum support member, said legs of said spider assembly flexing when the upper surface of its drum head is struck, thereby reducing damping of vibrations transmitted from said upper surface to said transducer and damping vibrations transmitted to said legs for reducing transmission of mechanical shocks to said drum support member.

Abstract
An electronic percussion synthesizer assembly incorporates a novel structure for supporting the drum heads. The novel supporting structure comprises a spider assembly (83) comprised of a plurality of legs (150) joined at one end for defining a hub (152) and secured at their free ends to the perimeter of the drum head (65) on the underside thereof. The spider assembly (83) minimizes mechanical damping of the striking surface and, where a plurality of drum heads (62, 63, 64, 65) are used, also minimiizes "cross talk" between the drum heads. A novel foot pedal control (120) for altering the sounds produced by the drum head is also disclosed.
