Abstract
A tone signal controlling apparatus for an electronic musical instrument comprising a body having a string corresponding portion, a movable performance member, and a sensor for detecting the action of the movable performance member with respect to the string corresponding portion, and generating a musical tone signal simulating a rubbed string instrument. The apparatus can control an electric signal simulating vibration of a string without any actual vibration of the string according the action of the movable performance member based on the output of the sensor, especially, by using signals representing a bow speed and a bow pressure which are applied to the string corresponding portion. Such special effects as vibrato can also be easily generated electrically. Owing to such electronic operability, the apparatus can also easily control the generation of the signal in accordance with a skill of a player.
