A music apparatus has a central processor, a plurality of generator modules, and a program memory storing instructions for causing the central processor to execute a process of synthesizing a musical tone signal with the generator modules. The process includes the steps of commanding each of the generator modules to generate a predetermined number of samples of the musical tone signal at a common sampling period, and collecting the samples from each of the generator modules and processing the collected samples at the common sampling period to thereby synthesize the musical tone signal. The generator modules include a synchronous generator module that does generate the predetermined number of the samples at the common sampling period, and an asynchronous generator module that does not generate the predetermined number of the samples at the common sampling period. The asynchronous generator module is commanded to perform the steps of generating an equivalent number of samples at a local sampling period, and converting the equivalent number of the samples arranged at the local sampling period into the predetermined number of the samples arranged at the common sampling period to thereby pass the predetermined number of the samples to the collecting step at the common sampling period.
