PURPOSE:To generate a musical sound rich in expression by generating a musical sound corresponding to both a percussing operation means and a percussed member at the time of percussing operation. CONSTITUTION:When a pedal 2 is tapped on, a hammer H is driven to percuss a pad P, a vibration sensor 1 on the side of the pad P detects vibration generated by the pad P by the percussion and outputs a corresponding shock signal, and an envelope detecting circuit generates and supplies an envelope signal to a sound source. On the side of the pedal 2, on the other hand, a pressure sensor detects the value of the pressure applied at the time of the tapping operation and a pressed membrane switch generates an ON signal. Then a counting circuit supplies the counted value of the membrane switch to the sound source and a tap position detecting circuit supplies the number of a switch far away from the base end part of the pedal 2 among membrane switches in ON states to the sound source. Then a sound system generates a musical sound. |
