Abstract: A tone generator comprises a basic wave memory for storing a first basic wave data of a musical tone signal, a differential wave memory for storing differential wave data between the first basic wave data and a second basic wave data which is different form the first basic wave data, and mixing device for mixing the first basic wave data and the differential wave data. The musical tone signal is produced by using the mixing device which mixes the basic wave data and the differential wave data without using directly stored sampling data memory. Further a multiplier for multiplying said differential wave data by random factors is provided, the random factors being distributed with normalized probability, resulting in that wave data not only varying tone color at random, but also resembling as a whole the basic wave tone color can be obtained.

Abstract: A formant tone generating apparatus provides n (where n=1, 2, . . . ) systems each capable of generating a pitch control signal by a timing of which period is n times longer than a fundamental pitch period of a musical tone including a formant tone to be generated. Then, a periodic function such as a sinewave function having a formant center frequency is modulated by use of a window function under control of the pitch control signal, so that a modulated signal is formed with respect to each system. Such modulated signals are synthesized together with respect to one or more systems, so that a synthesized signal is obtained. Based on the synthesized signal, the formant tone can be generated without forming unnecessary spectrum.

Abstract: In the production of a desired musical waveform by combining harmonic components corresponding to respective harmonic orders, the cut-off harmonic order q.sub.c, each harmonic component value is controlled by selecting the level Ha and the slope of the Formant filter characteristic. The cut-off harmonic order q.sub.c, the level Ha and the slope value can each be varied over a predetermined range. These operations can be performed with a simple circuit arrangement involving a small number of memories. Therefore, the present invention greatly contributes to the reduction of the size and the cost of electronic musical instruments.

Abstract: A tone generation system intended primarily for use in electronic musical instruments wherein a digital representation of a harmonically rich waveform is sampled, and a musical tone is produced therefrom. The stored waveform could be the four term Blackman-Harris window function, which has negligible side lobes and thus greatly attenuated higher harmonics. The stored function is read out at a fixed rate, but the time periods between successive readings of the waveform are varied to thereby vary the frequency of the output signal.

Abstract: An electronic musical instrument comprising a tone generator, an accumulator and a digital filter. The tone generator generates musical tone signals each represented by sampled values, corresponding to depressed keys. The accumulator accumulates the sampled values of the musical tone signals at predetermined timings. The digital filter modifies an output of the accumulator in accordance with the amplitude-frequency characteristic of a predetermined formant characteristic. A musical tone is produced based on an output of the digital filter circuit, thereby the formant characteristic is imparted to the musical tone.This utilization of the digital filter for the musical instrument makes it possible to impart a formant characteristic to a musical tone without a complex circuit construction. Moreover the insertion of the accumulator following the tone generator makes it possible to use the digital filter of a low speed type.

Abstract: In a digital tone synthesizer of a type using digital data representing the amplitudes of a predetermined fixed number of sample points along one cycle of the audio waveform of a musical tone and an oscillator controlling the sampling frequency as well as the pitch of the tone, a digital filter for transferring the digital data to a digital-to-analog converter at the sampling rate. The digital filter, in response to applied input coefficient values, operates as a low pass or high pass filter in which the cut-off frequency is a predetermined harmonic of the pitch frequency of the tone. By changing the coefficient values, the cut-off harmonic can be changed for a tone independently of the pitch of the tone. Thus any tone of the musical scale may be filtered to modify the harmonic content independently of the pitch of the tone.

Abstract: Waveform data representative of singing voices of a singing music piece are analyzed to generate melody component data representative of variation over time in fundamental frequency component presumed to represent a melody in the singing voices. Then, through machine learning that uses score data representative of a musical score of the singing music piece and the melody component data, a melody component model, representative of a variation component presumed to represent the melody among the variation over time in fundamental frequency component, is generated for each combination of notes. Parameters defining the melody component models and note identifiers indicative of the combinations of notes whose variation over time in fundamental frequency component are represented by the melody component models are stored into a pitch curve generating database in association with each other.
