A plurality of drum pads are each provided with a respective piezoelectric pick-up. The output of each piezoelectric pick-up is fed to a corresponding envelope-extracting circuit. The envelope signal extracted by the envelope-extracting circuit is converted by an A/D converter into a digital signal which is fed to a CPU. The CPU feeds a tone designation signal to a tone generator unit according to parameter data from a parameter data setter and the digital signals noted above, thereby causing generation of a corresponding drum sound.

An electronic musical instrument comprising means for generating an electric signal representing vibrations of a vibration member operative for musical performance, and tone generating means for generating a predetermined tone signal according to said electric signal from said signal generating mean

An electronic musical instrument comprising means for generating an electric signal representing vibrations of a vibration member operative for musical performance, and tone generating means for generating a predetermined tone signal according to said electric signal from said signal generating means, said electronic musical instrument further comprising: envelope-extracting means for extracting an envelope signal from said electric signal; analog-to-digital conversion means for converting said envelope signal from said envelope-extracting means into a digital signal; and control means for discontinuing the generation of tone from said tone generating means when the level of said digital signal from said analog-to-digital conversion means becomes a predetermined value or a value slightly lower than said predetermined value.
