Abstract
There is provided a musical tone reproducing apparatus which is capable of recovering proper timing of musical tone generation even in a situation where processing of events takes much time such that the sounding timing of musical tones is delayed. Duration data read out from a FIFOare added together by a duration forward counter. A comparator circuitcompares the count value of an absolute time counterand the count value of the duration forward counter, and delivers the comparison result i to a FIFO controllerwhen the former becomes equal to or more than the latter. The FIFO controllercauses the FIFOto read out event information and delivers the same to a decoder, which in turn converts the event information into tone generator control data having a format peculiar to a tone generatorand delivers the same data to a register write controller. The register write controllerwrites an associated tone generator parameter into a tone generator control register within the tone generator, and the tone generatorreproduces and outputs musical tones based on the tone generator parameter.
