Abstract
A digital pitch bend signal is supplied from an A/D converter to a first coefficient multiplier for every predetermined sampling period. An output of the first coefficient multiplier is added with an output of a second coefficient multiplier at an adder an output of which is delivered, as a digital pitch bend signal in the present cycle, from a buffer for the tone generation. The output of the adder is also fed back to an input of the second coefficient multiplier. Thus, from the buffer, a converted pitch bend signal having a value corrected during the respective sampling periods is produced.
