<p>A music and percussion system is described including a fully functional stringed hollow-body electric musical instrument (14), a floor unit (88), an interface unit (100a), and connecting cables (166a-166b). The instrument includes a microphone (56), a pickup (162a), and a plurality of transducers (16a-16d), also known as acoustic drum triggers, that are mounted on selected interior surfaces within the instrument neck (18) and body (20). By using a playing technique that combines strumming with tapping on the instrument neck or body, an instrumentalist is able to play the instrument strings and to simultaneously trigger sounds stored within a percussion synthesizer (138). Two transducers (90a-90b), each within a housing (92a-92b), are included in the floor unit (88). The instrumentalist may tap his or her feet on the housings to trigger additional sounds stored within the percussion synthesizer. Output signals from the instrument microphone, pickup, instrument transducers and floor unit transducers are transferred by appropriate electrical connections (94a-94e) to the interface unit (100a). The interface includes output jacks (124) that provide connections to a mixer, preamp (136), and percussion synthesizer by standard cables. The interface also includes a switching component that switches drum sounds whenever the instrumentalist breaks an infrared beam (108) that is transmitted from a sensor that is included in the floor unit (88). Certain switches included in the floor unit provide control of additional parameters of a percussion synthesizer including hi-hat position and patch selection. Units comprised of the inner components of the instrument described herein may be installed within existing stringed instruments.</p> |
