Abstract:
A method of generating waveform data on the basis of performance information, said method comprising:a waveform data generation step of generating waveform data for fixed or variable sections on the basis of performance information; a step of receiving a first or second command; a step of validating performance information in real time, when the first command is received; a step of, when said first command is received, issuing an instruction to said waveform data generation step for performing real-time generation of waveform data for each of the sections on the basis of the performance information validated in real time, in accordance with a generation start condition that predetermined timing has arrived; a step of, when said first command is received, reproducing the waveform data for each of the sections generated in real time by said waveform data generation step in response to said instruction; a step of, when said second command is received, issuing an instruction for performing non-real-time generation of waveform data for each of the sections, in accordance with a generation start condition that processing by said waveform data generation step has already been completed for a preceding section; a step of, when said second command is received, validating, in non-real time, performance information corresponding to each of the sections for which the non-real-time generation of waveform data is instructed; and a step of, when said second command is received, storing, into memory, waveform data generated by said waveform data generation step on the basis of the performance information validated in non-real time.
