<P>PROBLEM TO BE SOLVED: To provide an electronic drum solving a weak point, such as impossibility to sound a real musical tone signal, while employing the advantage of resonance system signal processing, such as absence of latency. <P>SOLUTION: When an impulse wave signal is generated and supplied, a resonance system signal processing part 20 generates the resonance system signal, and a PCM system signal processing part 30 reproduces and outputs a PCM system signal. Both the signals are amplified by gains 60, 62, respectively, both the amplified signals are mixed by a mixer 65, and the mixed signal is digital-to-analog-converted and sounded as an electronic drum sound from a speaker 50. A signal obtained by recording the reverberant sound of the actual electronic drum by a PCM technique beforehand is recorded on a memory 70, and the PCM system signal processing part 30 reads the recorded signal from a memory 70 at predetermined timing to be reproduced and output. <P>COPYRIGHT: (C)2010,JPO&INPIT |
