Abstract: A server system obtains markup code for a native application for client devices. The markup code is agnostic regarding types of client devices. The server system translates the markup code into a set of primitives. Client devices of multiple types running a native application send a request for content for the native application to the server system. The server system provides the set of primitives to the client devices of multiple types, and the client devices render the set of primitives in the native application.

Abstract: A foldable electronic percussion synthesizer assembly is disclosed that includes two fixed drum heads that are permanently mounted on the synthesizer housing and two movable drum heads that are mounted on respective movable support arms. Each support arm pivots the movable head between a folded position where its striking surface is juxtaposed to and faces the striking surface of a fixed drum head and an unfolded position where the striking surfaces of the fixed and movable head are substantially coplanar and separated from each other. The assembly includes vibration isolation means for each drum head that reduces crosstalk. A latch member is pivotably mounted to the vibration isolation means on the movable drum head to support the movable drum head in the unfolded position and secure the movable drum head on the fixed drum head in the folded position.
