ABSTRACT:
An electronic musical instrument includes a waveshape generator which generates first and second waveshapes having a pitch corresponding to a designated note. The first waveshape represents a complete waveshape produced by a certain musical instrument under a certain extreme condition (e.g., the hardest key touch). The second waveshape represents a complete waveshape produced by the same musical instrument under another extreme condition (e.g., the softest key touch). The electronic musical instrument further includes an interpolator which interpolates the first and second waveshapes in accordance with a playing condition (e.g., the strength of key touch) and produces and interpolated new waveshape as a waveshape of a musical tone to be produced. The introduction of this interpolator enables any waveshape under an intermediate condition to produce by preparing only two waveshapes under the two extreme conditions.
