ELECTRONIC MUSICAL INSTRUMENT HAVING TONE START PROMINENCE CIRCUIT

摘要

An electronic musical instrument having a conventional music playing circuit arrangement with a tone signal passage including tone generators, tone keyers, tone coloring filters, an amplifier and a loudspeaker is further provided with a tone start prominence circuit arrangement. The arrangement comprises an amplitude modulator inserted in the tone signal passage, a detector connected to the tone signal passage for detecting the start of the tone signal being played, and a waveform shaper producing a percussive waveform signal upon receipt of the detected signal and controlling the modulator so that the start of the tone signal be percussively emphasized. As an improved embodiment, a tone color modulator is further inserted in the tone signal passage and is controlled by the above-mentioned detected signal, thereby emphasizing the start of the tone signal more clearly.
