ABSTRACT:
A pitch is extracted from an input waveform signal, and a musical tone having a corresponding tone pitch is generated. In this case, a signal intensity at the leading edge of the input waveform signal is detected to determine a tone volume of the musical tone. A change degree of the signal intensity at the leading edge of the input waveform signal is detected to determine a timbre of the musical tone. As a result, the tone volume and the timbre of the output musical tone can be independently controlled in accordance with a music performance manner, and an improvement of a performance effect is expected.
