Claims

[Claims for Utility Model Registration] (1) Detection means for detecting the mounting position of the pitch bend at initialization in an electronic musical instrument with a pitch bend that converts the output of the pitch bend into an A/D converter and generates a musical tone using a digital signal based on the converted output. and a pitch bend device having data setting means for setting the detected value as pitch bend center position data when the detection result by the detection means is within a predetermined range, and incidentally setting dead zone data of a predetermined value for data correction. electronic musical instrument. (2) If the detection result is not within a predetermined range, the data setting means sets specific value data as pitch bend center position data, and sets other value data different from the dead zone data of the predetermined value. An electronic musical instrument with a pitch bend according to claim 1, which is a means for additionally setting dead zone data.
