ABSTRACT:
An electronic musical instrument including: a scraper operator having a predetermined operation length in a predetermined operation direction, for detecting at least one of access, contact, and push of an operating member, and generating a plurality of signals to be detected within the range of the operation length; a time interval generating unit for receiving the signals detected by the scraper operator and generating a time interval signal representing a time difference between consecutively detected signals; and a tone signal synthesizer for generating a tone signal in accordance with the detected signal and the time interval signal each time the scraper operator generates the signal to be detected. Signals indicating the position, speed, and acceleration are derived from a plurality of consecutive signals time sequentially detected, providing various control ways of musical tone signals.
