Patent number: 6066793Abstract: In executing a music performance on the basis of supplied performance data, a feeling of swing can be imparted to the performance by delaying tone-generation start time of a tone, based on the performance data, at each predetermined beat such as upbeat. In this case, if an original tone-generation end time of the tone to be delayed is ahead of tone-generation start time of a next tone, control is executed to automatically change a duration of the tone in such a manner that actual tone-generation end time of the delayed note comes ahead of the tone-generation start time of the next tone. In this manner, the delay control can be properly executed on staccato performance data without losing characteristics of staccato.Type: GrantFiled: April 9, 1998Date of Patent: May 23, 2000Assignee: Yamaha CorporationInventors: Yoichiro Ogai, Takao Yamamoto

Patent number: 5831192Abstract: In a musical system, a transmitting device transmits performance data, a first receiving device is connectable to the transmitting device to receive and pass the performance data, and a second receiving device is connectable subsequently to the first receiving device to receive therefrom the performance data. The transmitting device operates to transmit first performance data arranged to drive a first sound source to generate musical tones and to transmit second performance data arranged to drive a second sound source of a type different than the first sound source. The first receiving device operates if the same has the first sound source for admitting the first performance data so as to drive the first sound source and for issuing a control message to the second receiving device. The second receiving device having the second sound source operates in response to the control message to prohibit admission of the second performance data to thereby disable the second sound source.Type: GrantFiled: January 24, 1997Date of Patent: November 3, 1998Assignee: Yamaha CorporationInventors: Koichiro Watari, Yoichiro Ogai

Patent number: 5786541Abstract: A musical tone synthesizing apparatus is used to synthesize musical-tone waveforms on the basis of simulation of a tone-generation mechanism of a musical instrument. Herein, a drive signal is generated based on an excitation envelope signal in accordance with a manipulation of performance made by a human operator (e.g., performer) and is then converted to an excitation signal in accordance with an operating behavior of the musical instrument. For example, the operating behavior indicates a behavior of a reed portion of a wind instrument to which breath is blown in; or it indicates a behavior of a string of a stringed instrument which is striken or plucked. The excitation signal is input to a physical-model sound source realizing resonating-body/vibrating-body models. The physical-model sound source performs calculations, simulating the tone-generation mechanism of the musical instrument, on the excitation signal to produce a musical tone signal.Type: GrantFiled: May 14, 1997Date of Patent: July 28, 1998Assignee: Yamaha CorporationInventors: Takeshi Komano, Yoichiro Ogai

Patent number: 5670728Abstract: A pitch-asynchronous-type musical tone creating apparatus, provided for an electronic musical instrument, comprises at least a waveform memory, a low-pass filter and an interpolation section. Waveform samples, stored by the waveform memory, are sequentially read out, so that the interpolation section performs interpolation process on the waveform samples to create interpolation samples. Musical-tone parameters, such as a tone-color characteristic and an envelope characteristic, are imparted to the interpolation samples so as to create musical-tone samples. When performing reading operations on the waveform memory at a high speed which causes skipping of the reading operations, certain frequency components, which cause occurrence of folding noises, are incorporated into the interpolation samples. Those frequency components are removed from the waveform samples, read from the waveform memory, by the low-pass filter whose cut-off frequency is determined responsive to a frequency number.Type: GrantFiled: May 9, 1995Date of Patent: September 23, 1997Assignee: Yamaha CorporationInventors: Yoichiro Ogai, Masahiro Shimizu

Patent number: 5641931Abstract: In a device which excites an oscillating signal in a closed loop containing a delay circuit and a filter so as to synthesize a sound of pitch corresponding to the total delay time in the closed loop, arithmetic operations are performed in the closed loop, in response to a change in a color controlling coefficient caused during generation of the sound, for interpolating delayed output signals from plural points in the loop having different delay time. This interpolation compensates for a variation in the signal delay time in the closed loop resultant from the change in the filter coefficient, to allow the entire closed loop to provide such a total delay time that excites oscillation corresponding to a desired pitch. The closed loop also includes first and second filters.Type: GrantFiled: March 28, 1995Date of Patent: June 24, 1997Assignee: Yamaha CorporationInventors: Yoichiro Ogai, Iwao Higashi

Patent number: 5602358Abstract: An effect imparting device is constructed such that effects of a first kind which are different from each other are imparted to at least two of a plurality of musical tone signals transmitted via a plurality of channels. At least two of the musical tone signals are mixed. An effect of a second kind is imparted to the resulting signal. The effect imparting device is adapted to bypass at least one of effect-imparting blocks. An electronic musical instrument can change one of the effects of the first kind corresponding to a tone color of at least one of the musical tone signals transmitted via the channels simultaneously when the tone color is changed, while changing of an effect of the second kind is inhibited. A plurality of output terminals are provided through which the musical tone signals of the channels and to which effects have been imparted can be output to an external device, in a manner independent of each other.Type: GrantFiled: September 13, 1994Date of Patent: February 11, 1997Assignee: Yamaha CorporationInventors: Takao Yamamoto, Yoichiro Ogai, Kiyoshi Hasebe

Patent number: 5442130Abstract: The musical tone synthesizing apparatus utilizes a loop circuit receptive of an input signal for looping the same with a given delay time to produce an output signal representative of a musical tone. The loop circuit includes a delay element for delaying the input signal and a feedback path for feeding back the delayed input signal to the delay element. A control unit is provided for controlling the delay element according to a designated pitch of a musical tone so as to set the delay time of the loop circuit to thereby determine the pitch of the musical tone. A generator generates the input signal containing various frequency components. A high-pass filter is connected precedingly to the loop circuit for selectively attenuating relatively lower frequency components of the input signal, which have periods longer than the set delay time of the loop circuit.Type: GrantFiled: March 2, 1993Date of Patent: August 15, 1995Assignee: Yamaha CorporationInventors: Toru Kitayama, Yoichiro Ogai
