Abstract
A musical tone control apparatus controls an electronic musical instrument which simulates a natural musical instrument such as a bowed instrument. The apparatus includes an operator which can be movably operated in a predetermined direction and simulates a bow, a converter which stores a plurality of nonlinear characteristics. The nonlinear characteristics represent a relation between pressure signal which is added on the operator by a player and control pressure signal which simulates real rubbing pressure added on the string. To realize real performance by the bow, the converter converts the pressure signal into the control pressure signal to be changed in accordance with the position of the operator even if the pressure signal is constant.
