摘要： In order to simulate sounds of an acoustic musical instrument such as a bowed stringed instrument, an electronic musical instrument employs a musical tone control apparatus which at least contains an operating device and a detecting circuit. Herein, when operating the operating device which can be operated in a two-dimensional area, the detecting circuit detects operation information corresponding to an operating position or an operating displacement of the operating device. Then, velocity information is generated based on the operation information. Thereafter, a musical tone is generated in response to a musical characteristic corresponding to the velocity information under a condition where the operating device is now operating. Preferably, the operating device is configured by a digitizer on which surface an electronic pen is moved two-dimensionally by the performer. Thus, it is possible to impart the varied performance expression to the musical tone to be generated.

摘要： An electronic musical instrument has an electronic sound source of a physical model simulating the sound mechanism of an acoustic mechanical instrument, in particular, a stringed instrument of the bowing type. The electronic sound source is controlled according to tone pitch information and tone information determining a characteristic of a musical tone to be generated. A keyboard is provided as a data input device by which tone pitch is designated and on which a performance manner is expressed via initial touch and after touch. A memory stores two sets of performance information, each set containing bowing force and bowing velocity information. An interpolating unit operates to access the memory for carrying out interpolation between the two sets of performance information according to the performance manner, and produces respective interpolated performance information regarding bowing force and bowing velocity information effective to control the artificial sound source. The electronic sound source is also controlled by the interpolated performance information.
