PURPOSE:To provide a musical tone synthesizer which is capable of simulating not only struck stringed instruments but also plucked string instruments and percussion instruments, etc., as well and is capable of making simulation meeting the characteristics of driving objects and execution. CONSTITUTION:Respective parameters are generated from a control section 9 when performance operators 8 are operated. Reflection force signal waveforms from a string speed filter 11 are varied in amplitude with time by reflection coeffts. (REG) and are supplied as the subtraction signals from driving waveforms (DRVWAVE) to an adder 13. The outputs from this adder 13 are so supplied to adders 2, 6 as to drive a loop circuit 20. The synthesized musical tone is taken out of the arbitrary positions of the loop circuit 20. The generation timing of a trigger (KON1), trigger (KON2) is controlled according to the execution and the kinds of the musical instruments. |
