Abstract
A digital musical tone signal is generated in a first LSI selected by a chip select signal transferred from a CPU in accordance with a control signal transferred through a control bus from the CPU. Amplitude data and envelope data are transferred from a second LSI to the first LSI through data lines. In the first LSI, the digital musical tone signal amplitude- and envelope-controlled is transferred to an A/D converter where it is converted into an analog musical tone signal.
