摘要： 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.

摘要： An electronic musical instrument is of a harmonic synthesis type and is provided with an order number memory device which stores a plurality of order numbers of the harmonic components necessary to form respective tone colors, an amplitude coefficient memory device which stores a plurality of sets of amplitude coefficients for the respective harmonic components corresponding to the respective order of numbers stored in the order number memory device, and a tone color selector which controls the order number memory device and the amplitude coefficient memory device, when a certain tone color is selected, for causing the respective memory devices to produce the order numbers and the amplitude coefficients of a set corresponding to the selected tone color. According to the order numbers, respective harmonic component waves of a certain amplitude are produced and are multiplied with the amplitude coefficients and the multiplication products thus obtained are combined to synthesize musical tones having the selected tone color.By providing only necessary order numbers and coefficients, the memory size becomes small and the synthesizing speed becomes high.

摘要： In a musical instrument having one or more tone generators in which a plurality of data words corresponding to the amplitudes of a corresponding number of evenly spaced reference points defining the waveform of one cycle of an audio signal are transferred sequentially from a note register to a digital-to-analog converter in repetitive cycles at a rate proportional to the pitch of the tone being generated, apparatus is provided for adaptively computing the set of data points in response to values of preselected harmonic coefficients. The computation apparatus advances past all harmonic coefficients of smaller magnitude than a selected threshold thereby reducing the computation time and making the instrument capable of responding to time varying tonal changes.

摘要： A keyboard operated tone synthesizer with glissando effect in which actuating individual keys successively on a keyboard produces all the intermediate notes of the chromatic scale. The time interval between notes in the scale is independently controllable. In one modification of the invention the individual notes of the chromatic scale played during the glissando, when played slowly enough to be heard individually, can be controlled in attack, decay, sustain and release characteristics. The chromatic glissando can move either up or down the scale, depending upon the pitch of each key relative to the previous key played on the keyboard.

摘要： The electronic musical instrument according to the invention is capable of controlling each level of harmonics constituting a musical tone individually and independently from each other and thereby producing a musical tone which is a close simulation of a natural musical tone. In order to produce change in the level of each harmonic with the lapse of time separately and independently, information respectively representing a peak level of attack, attack time from start of generation of a tone to the peak level, a sustain level and decay time from the peak level to the start of the sustain level is memorized for each harmonic and the level of each harmonic is controlled in response to such information.In one example of the electronic musical instrument, the level of each harmonic constituting a musical tone is amplitude-modulated with a different period and depth.

摘要： Sliding overtone generation is implemented in a computor organ of the type disclosed in U.S. Pat. No. 3,809,786. In such an instrument, the sampled amplitudes of a musical waveshape are computed in real time by individually calculating the amplitude contributions of the Fourier components constituting the waveshape. In accordance with the present invention, one or more of these Fourier components is evaluated at a frequency which varies with time. The resultant overtone "slides" up or down in frequency between preselected limits at a controllable rate of "slide speed". Unusual tonal effects are achieved.

摘要： The production of musical notes containing anharmonic overtones is implemented in a computor organ of the type disclosed in U.S. patent application Ser. No. 225,883, filed Feb. 14, 1972, and now U.S. Pat. 3,809,786. In such an instrument, the sampled amplitudes of a musical waveshape are computed in real time by individually calculating the amplitude contributions of the Fourier components constituting the waveshape. In accordance with the present invention, certain of these Fourier components are evaluated at frequencies offset from multiples of the nominal fundamental frequency of the note being generated. This is accomplished by utilizing in the overtone amplitude calculations offset values Eta which establish the extent of anharmonicity of each overtone. This results in complete freedom of control of the anharmonicity of individual overtones. The overtone offset ( Eta ) values may be stored in a memory, or may be generated by appropriate circuitry. In certain embodiments the offset is proportional to the frequency of the note being produced, preferably being a constant number of cents. Other embodiments include, among other things, constant frequency offset independent of time, time variant anharmonicity, offset of alternate overtones in opposite frequency directions, and overtone selection to insure correct frequency of a subjective fundamental.
摘要翻译：包含非和谐色调的音符的制作在美国专利申请系列公开的类型的计算机器中实现。 1972年2月14日提交的第225,883号， 3,809,786。在这种仪器中，通过分别计算构成波形的傅立叶分量的振幅贡献，实时地计算乐音波形的采样振幅。根据本发明，这些傅立叶分量中的某些以与正在产生的音符的标称基频的倍数偏移的频率进行评估。这是通过利用确定每个泛音的非谐波程度的泛音振幅计算偏移值等来实现的。这样就可以完全控制个人色调的非平和性。泛音偏移（eta nu）值可以存储在存储器中，或者可以由适当的电路产生。在某些实施例中，偏移量与正在产生的纸币的频率成比例，优选为恒定数量的分。其他实施例除了别的以外包括与时间无关的恒定频率偏移，时变非平稳性，在相反频率方向上的交替泛音的偏移，以及泛音选择以确保主观基础的正确频率。
