PROBLEM TO BE SOLVED: To form musical tone waveform samples without interruption of reproduced waveform data. SOLUTION: When the total computation quantity calculated in S360 is excessive and if the total computation is carried out as it is, the computation does not end before the timing to be read out by a reproducing section 9. If the interruption of the reproduced waveform data is decided, the computation cycle CC of the sound production channel made after the order of the computation of the prescribed order by S370 is decreased by the number of the samples formed by '+1' by as much as needed. Consequently, whether the total computation quantity is confined within a prescribed range or not is decided in S380 and when this quantity is decided to be within the prescribed range, the channel control processing ends but when the computation quantity is decided to still exceed the prescribed range, silencing channels are determined successively from the channel decided to be the last of the computation order in S390 and the silencing processing is executed. |
