摘要： For each one note or for each plurality of notes constituting a reference tone, a segment setting section (42) segments a time series of actual pitches of the reference tone into one or more note segments. For each of the one or more note segments, a relativization section (44) creates a time series of relative pitches that are relative values of individual ones of the actual pitches of the reference tone to a normal pitch of the note of the note segment. Information registration section (38) stores, into a storage device (14), relative pitch information comprising the time series of relative pitches of each individual one of the note segments. The segment setting section (42) may use musical score data, time-serially designating the notes of the reference tone, to set each of the note segments for each note designated by the musical score data, and may correct at least one of start and end points of each of the set note segments in response to user's operation.

摘要： A pitch synchronizing signal snychronized with the pitch of a digital tone signal to be filtered is generated by a pitch synchronizing signal generation circuit. A digital filter circuit which receives the digital tone signal and imparts it with a desired tone color by subjecting it to a proper filter operation executes this filter operation with a sampling period synchronized with the pitch synchronizing signal. A moving formant thereby is realized which is suitable for control of a tone. A pitch synchronization output circuit for sampling and outputting the output of the digital filter circuit in accordance with the pitch synchronizing signal may be provided and this will prevent occurrence of a sampling noise. A switching circuit is provided for enabling switching order of the digital filter circuit between an even number and an odd number. By this switching of order, a desired filter characteristic can be realized with high fidelity. The filter coefficient may be used commonly for two orders positioned at symmetrical positions. Filter coefficients which do not undergo timewise change and those which undergo timewise change may be selectively supplied in separate channels.

摘要： A fixed formant filter for a digital electronic instrument of the type in which musical tones are generated from waveshape data calculated independently of frequency of the tone from constituent generalized Fourier components. The Fourier components are individually scaled by scale factors selected from a set of stored scale factors which define the transfer characteristic of the fixed formant filter. Each separately addressable stored scale factor corresponds to a different frequency value in the musical scale. A scale factor is selected for separately scaling each harmonic of the tone generated in response to the particular note of the musical scale keyed on the instrument. The selected scale factors may be modified by a frequency deviation signal to provide vibrato or other frequency modulation effects. The selected scale factors are also corrected for any frequency deviation between the actual frequency of the harmonic of the keyed note being scaled and the frequency value associated with the selected scale factor.

摘要： A vocoder system for improving the performance expression of an output sound while lightening the computational load. The system includes formant detection means and division means in which the center frequencies have been fixed. The modulation level with which the levels of each of the frequency bands that have been divided in the division means are set by a setting means based on the levels of each of the frequency bands that correspond to those that have been detected in the formant detection means and formant information with which the formants are changed. Therefore, it is possible to improve the performance expression of the output sound with a light computational load and without the need to calculate and change the filter figure of each filter for each sample in order to change the center frequency and bandwidth of each of the filters comprising the division means.

摘要： A system and method are disclosed for independently adjusting the pitch and timbre of an input signal within a modified Lent shifter. A method of adjusting the pitch and timbre of an input signal includes receiving an input signal and determining a window length corresponding to the input signal. A finite length spectrally smoothed signal is created from the input signal by synchronously windowing the input signal. The timbre of the finite length spectrally smoothed signal is adjusted thereby creating a finite length timbre adjusted signal. The finite length timbre adjusted signal is recombined at a rate necessary to produce a desired output pitch thereby reducing artifacts introduced by processing the finite length timbre adjusted signal and minimizing latency between receiving the input signal and producing a desired output signal.

摘要： The content of component waveforms of at least one signal is changed in a variety of ways among the formant center signals that are synthesized with the formant waveform signals, making it possible to arbitrarily change the waveform of a musical tone that is generated. To cope with changes in the formant waveform signals Ffj(t) or the formant carrier signals Gj(t) formed by synthesizing the component waveforms, furthermore, the signals Fj(t) and Gj(t) are weighed and interpolated. This permits the signals Fj(t) and Gj(t) to change smoothly. Moreover, the number or combination of formant waveform signals synthesized to produce a musical tone is controlled depending upon the musical factors, elapsed time of sounding, envelope levels, envelope phases and/or settings instructed by an operator. This enables the form of the synthesized formant to be changed and the content of a musical tone that is generated to he changed in a variety of ways.

摘要： A musical tone signal synthesizer wherein a first waveform signal of a frequency defined by first frequency information is produced as a modulation signal, a second waveform signal indicative of a windowing function is produced at a cycle defined by second frequency information and a third waveform signal starting from a predetermined phase at each cycle of the second waveform signal is repeatedly produced at a shorter cycle than that of the second waveform signal, and wherein the second and third waveform signals are modulated by the first waveform signal and multiplied to produce a fourth waveform signal as a musical tone signal having a fixed formant characteristic comprised of a plurality of formants.
