Abstract:
A tone generating device comprising:a supply unit for supplying performance information;a storage unit for storing therein a plurality of programs including a tone generating program; anda general-purpose arithmetic processing unit capable of concurrently executing the programs stored in said storage unit in a parallel manner, said arithmetic processing unit causing a plurality of internal interrupt signals to be generated within a predetermined time period and activating the tone generating program to generate tone data based on the performance information that is supplied by said supply unit in response to the internal interrupt signals,wherein the tone generating program activated by said arithmetic processing unit includes an adjusting mechanism for variably adjusting an amount of a tone waveform to be generated, in such a manner that a predetermined number of samples of tone data can be cumulatively formed within the predetermined time period by tone data forming operations being effected only when the tone generating program is actually activated by said arithmetic processing unit.
