Autocorrelation tone generator for an electronic musical instrument |
摘要 |
A keyboard operated electronic musical instrument having a number of tone generators which are assigned to actuated keyswitches. A tone selection means is implemented comprising an autocorrelation function generator. A set of harmonic coefficients is created by means of a discrete Fourier-cosine transformation of the autocorrelation function. A computing means transforms the harmonic coefficients to musical tones. The generated musical tones are varied in tone color by selecting the shape of the autocorrelation function. A means is provided to vary the autocorrelation function in a time variant manner in response to a control signal.
