Abstract
A sound aspect generating apparatus for an electronic musical instrument is adapted to interpolate between respective parameters constituting two kinds of designated sound aspects to generate sound aspects based on the interpolated parameters. More specifically, preset switches (71 to 7n) are operated to read out the parameters of the two kinds of sound aspects stored in advance in a memory (50). By designating an arbitrary point between two kinds of sound aspects with the aid of a controller (10), the rate of change of the respective parameters between the designated sound aspects is evaluated by means of a central processing unit (40) and the parameters interpolating the portion between the designated two points are evaluated by the central processing unit based on the above mentioned rate of change. The evaluated parameters are converted into an analog signal which is applied to a music synthesizer as sound aspects, whereby a musical tone signal is produced.
