Abstract: An in-vehicle drum simulator and mixer for enabling an automobile passenger to create and overlay percussive sounds onto the audio portion of a radio, tape player, cassette disk player, and the like. One or a plurality of touch sensors distributed in selected locations within the vehicle provide electronic input signals upon impact to a drum simulator which generates an output signal in relation to the particular impacted touch sensors. An audio mixer receives the drum simulator output signal and an output signal form the radio, or the like audio signal source, and overlays the drum sounds onto the radio output signal. Thus, the passenger can actively play along with the radio.
