Tone generator device for driving light emitting elements

A method for driving a plurality of light emitting elements in response to tone generation, which comprises:

• a step of sequentially reading out tone generating sequence data in accordance with a performance sequence and decoding tone generation control parameters from the read-out sequence data;
• a step of sequentially writing the decoded tone generation control parameters into a control register;
• a step of generating tone signals on the basis of the tone generation control parameters written in said control register;
• and
• a step of performing control to sequentially output, on the basis of the tone generation control parameters written in said control register, pattern data from a pattern register that stores pattern data representing a time series of driven states to be taken by said plurality of light emitting elements.

• a step of sequentially reading out tone generating sequence data in accordance with a performance sequence and decoding tone generation control parameters from the read-out sequence data;
• a step of sequentially writing the decoded tone generation control parameters into a control register;
• a step of generating tone signals on the basis of the tone generation control parameters written in said control register;
• and
• a step of performing control to sequentially output, on the basis of the tone generation control parameters written in said control register, pattern data from a pattern register that stores pattern data representing a time series of driven states to be taken by said plurality of light emitting elements.
