Abstract:
A method of synthesizing a musical tone signal by executing a control program and a plurality of generator programs with a processor,wherein the control program is executed to perform the steps of:commanding each of the generator programs to generate a predetermined number of samples of the musical tone signal at a first sampling period; andcollecting the samples from each of the generator programs and processing the collected samples at the first sampling period to thereby synthesize the musical tone signal, and,wherein the generator programs include a synchronous generator program that does generate the predetermined number of the samples at the first sampling period, and an asynchronous generator program that does not generate the predetermined number of the samples at the first sampling period, the asynchronous generator program being executed to perform the steps of:generating an equivalent number of samples at a second sampling period in response to the commanding from the control program, the equivalent number of the samples arranged at the second sampling period being determined to correspond to the predetermined number of the samples arranged at the first sampling period, andconverting the equivalent number of the samples arranged at the second sampling period into the predetermined number of the samples arranged at the first sampling period to thereby pass the predetermined number of the samples to the control program at the first sampling period.
