Multi-channel stereophonic sound reproducing system for electronic musical instruments

摘要: The multi-channel stereophonic sound reproducing system includes tone generators for generating signals each having a predetermined pitch and keyers arranged to derive from the signal corresponding depressed one of plurality keys juxtaposed in order musical notes. Each derived through is applied preselected coloring filters frequency characteristics different other. Output are supplied via individual resistors points longitudinal direction an elongated resistor body form composite signal. separated into components at other between adjacent ones first-mentioned points. All sections including volume controlled amplifier loudspeakers disposed spacious hall or room substantially equal interval reproduce therefrom desired sounds.
