Abstract
A musical tone synthesizing apparatus is disclosed wherein an excitation signal corresponding to performance data is generated and supplied to a loop circuit. In the loop circuit, this excitation signal is delayed for at least a fixed time period and a repeatedly circulating muscial tone signal is generated. At the beginning of the generation of this musical tone signal, a initial signal with a frequency which corresponds to the pitch of the generated musical tone is supplied. As a result of this, in the loop circuit, resonant operation is carried out quickly in accordance with the initial signal.
Claims7
A musical tone synthesizing apparatus comprising:
- (a) excitation means for generating an excitation signal based on performance data;
- (b) a loop circuit connected to the excitation means and including at least delay means provided with a predetermined delay time, said excitation signal being supplied to and repeatedly circulating through said loop circuit to form a musical tone signal which is outputted from said loop circuit means;
- and
- (c) initial signal generation means for generating an initial signal having a frequency which corresponds to a desired tone pitch of said musical tone signal, and supplying said initial signal to said loop circuit.
