Abstract
PURPOSE: To obtain diversified and various musical tones with a simple constitution by reading out music sheet information according to play programs through a CPU from a memory and driving the musical tone waveform generator formed of resistance networks, etc. through registers.
CONSTITUTION: A CPU 1 which is controlled of start and end of the like by a control panel 2 reads out music sheet information such as notes, note lengths, tempo marks, scales, etc. corresponding to the music havisng been stored in a music sheet information memory 3 subsequently according to the read-out of a play program memory 4 and transfer the information to the respectively corresponding registers of a register 5. As a result, the musical tone waveforms corresponding to the music are generated from a musical tone waveform generator 6 formed of the resistance networks, etc, provided with the power source applying electrodes 12... connecting to a power source applying circuit 13 and the potential detecting electrodes 10... connecting to a scanning circuit 11, based on the information having been temporarily stored in the registers. At the same time, the transfer of the next music sheet information from the CPU 1 into the register 5 is accomplished through an interrupt control circuit 7, thus the long-term playing through generation of diversified and various musical tones may be accomplished with the simple constitution.
