Abstract
PURPOSE: To generate musical signals by storing a plurality of groups of amplitude coefficients for the components of fundamental and high frequencies constituting the musical sounds to generate a plurality of time functions so that the groups of amplitude coefficients and time functions are combined, multiplied and summed.
CONSTITUTION: Address signals An are fed to memories of amplitude coefficient groups of different kinds 41 and 42 and addressed so that the amplitudes Y1(n) and to multipliers 45 and 46. Other multipliers 43 and 44 are driven by a detector 40, which is operative to detect the condition of a key board switch 12, and time functions A1(t) and A2(t) are fed to the multipliers 45 and 46 so that they may be multiplied. The outputs of the multipliers 45 and 46 are multiplied with the sine value Sin(π/W)ngR, and the multiplied values are added by an adder 49. The added value F(n)' is fed to an accumulator 16. Thus, it is possible to generate the musical sounds, which have their tones timely varied and which are excellent in naturality, with the use of a small number of memories
