Abstract
A musical sound generating system which generates musical sounds having desired tone regardless of the variation of volume setting. In the musical sound generating system, the standard tone control touch curve TCstd, the maximum tone control touch curve Tcmax, and the minimum tone control touch curve TCmin when the amplification factor V is standard (a standard amplification factor Vstd), maximum, and minimum respectively are stored. If the amplification factor is higher than the standard amplification factor Vstd, an interpolation between the standard tone control touch curve TCstd and the maximum tone control touch curve TCmax is performed, and the tone control touch curve TC according to the amplification factor V is obtained. Based on the tone control touch curve, the cut-off frequency F corresponding to the velocity value Tv is determined, and then the tone of the musical sound is controlled by the low pass filter with the cut-off frequency F.
