Claims

[Scope of utility model registration request]

A sound source memory in which digital data of a plurality of single tones is written in advance, designated address output means for outputting a designated address of the tone signal when transmitting the tone signal of each line, and an intermittent interval and combination of each of the single tones. The formation sequences of various tone signals to be formed are written in advance, and each of the formation sequences is selectively designated by the specified address, and the digital data of each single tone is stored in the sound source memory based on the specified formation sequence. A digital device comprising: a sequence memory that outputs a data read address; and tone signal sending means that sends tone signals formed by analog conversion of digital data read from the sound source memory when sending tone signals of each line. Converter tone signal generation circuit.
