Abstract
A detector is provided which generates detection signal that represents a value varying in response to the movement of a key operated on a keyboard. The key operating style employed for the operated key is reflected in subtle, dynamic action occurring in connection with the operated key during depression of the key. For instance, if the key operating style for the operated key has more staccato factor or characteristic, then the action of the operated key will present nonlinear characteristics relatively remarkably. Thus, the key operating style for the operated key can be determined on the basis of time-varying values of the detection signal, and by controlling tone depending on the determined key operating style, it is possible to achieve good-quality tone control, well reflecting subtle differences in key operating styles such as staccato, tenuto and the like, which is difficult to achieve with the conventional touch control techniques.
