  • Patent number: 10541003
    Abstract: A content reproduction screen displays a plurality of content items. A video reproduction processing section reproduces substantially simultaneously videos of a plurality of content items on a screen. An audio reproduction processing section reproduces substantially simultaneously audio signals of a plurality of content items. During reproduction of a plurality of content items, a comparison is made between a current reproduction position of the audio signal in an audio reproduction processing section and a current reproduction position of each video in the video reproduction processing section, and, if a discrepancy between the compared current reproduction positions is equal to or greater than a threshold value, the current reproduction position of the video is corrected on the basis of the current reproduction position of the audio signal. In this way, the current reproduction position of each video is synchronized with the reproduction position of the audio signal.

  • Patent number: 8106286
    Abstract: In a synthesizer 10, when a function of a tone generation module 312 provided by an external tone generation server 310 is usable, a tone generator control module 102 assigns a necessary number of sound generation channels among sound generation channels of an internal tone generation unit 17 and sound generation channels of the external tone generation module 312, for sound generation corresponding to MIDI data. When assigning the sound generation channel of the tone generation module 312, the tone generator control module 102 transmits, to the tone generation server 310, the MIDI data with identification information of the assigned sound generation channel, thereby causing the sound generation channel indicated by the identification information in the tone generation module 312 to generate waveform data according to the transmitted MIDI data.

  • Patent number: 7875789
    Abstract: A synthesizer 10 is configured such that when a PC 30 is connected thereto, the synthesizer 10 accepts selection of a tone used for sound generation from among a tone included in an internal tone generation unit 16 and a tone included in a tone generation module 312 provided by the external PC 30, and causes the PC 30 to enable the function of the tone generation module 312, downloads an edit operation accepting program corresponding to the tone generation module 312 from a UI control program memory 315 of the PC 30, and executes the downloaded edit operation accepting program to thereby realize a function of editing data of the tone included in the tone generation module 312, the data being stored in the PC 30, when the tone included in the tone generation module 312 of the PC 30 is selected.

  • Patent number: 6816833
    Abstract: An audio processing apparatus is constructed for generating an auxiliary audio signal based on an original audio signal and mixing the auxiliary audio signal to the original audio signal. In the apparatus, a control section designates a pitch of the auxiliary audio signal. A processing section processes the original audio signal under control of the control section to generate the auxiliary audio signal having the designated pitch, and applies a first effect to the generated auxiliary audio signal. An effector section applies a second effect different from the first effect to the original audio signal. An output section outputs the original audio signal applied with the second effect concurrently with the auxiliary audio signal applied with the first effect. The control section may control the processing section to alter the first effect dependently on a difference between a pitch of the original audio signal and the designated pitch of the auxiliary audio signal.

  • Patent number: 6657114
    Abstract: Sound signal indicative of a human voice or musical tone is input, and the pitch of the input sound signal is detected. Then, a scale note pitch is determined which is nearest to the detected pitch of the input sound signal. In the meantime, a scale note pitch of an additional sound or harmony sound to be added to the input sound is specified in accordance with a harmony mode selected by a user. The scale note pitch of the additional sound to be generated is modified in accordance with a difference between the determined scale note pitch and the detected pitch of the input sound signal. Because the additional sound is generated with the modified pitch, it can appropriately follow a variation in the pitch of the input sound to be in harmony with the input sound, rather than exactly agreeing with the scale note pitch.

  • Patent number: 6369311
    Abstract: A harmony tone generating apparatus receives a voice wave signal bearing musical tone pitches such as a singer's or a speaker's human voice signal and a musician's instrumental voice signal, and plural kinds of performance data, each representing a musical note pitch, from plural kinds of performance sources. The latest received performance data from among the plural performance sources is captured and supplied to a harmony tone data generator, which in turn generates harmony tone data defining a tone pitch which is determined by the note pitch represented by the performance data. As the harmony tone data generator includes a limited number of data generation-channels, the limited number of the latest captured performance data pieces are assigned thereto for harmony data generation, truncating the oldest supplied performance data for new data assignment, where there is no empty channel left and newly captured performance data is supplied.

  • Patent number: 6307140
    Abstract: A music apparatus is constructed for receiving an input signal composed of either of a voice signal and a tone signal and for processing the input signal based on a timbre change command signal to generate at least one channel of an output signal. In the music apparatus, a reference pitch designation section designates a reference pitch. An output signal generation section receives the input signal, the timbre change command signal and the reference pitch designated by the reference pitch designation section for changing a timbre of the input signal in accordance with the timbre change command signal, and for changing a pitch of the input signal above or below the reference pitch in accordance with the timbre change command signal, thereby generating the output signal having the changed timbre and the changed pitch.

  • Patent number: 5777251
    Abstract: An electronic musical instrument apparatus includes a pad and fret switches. When the pad is stricken while any one of the fret switches is depressed, at least a musical tone is generated. The apparatus has different modes of performance operation including a first melody mode, a second melody mode, a base mode, a first chord mode, a second chord mode, an ad-lib mode and the like. In the first melody mode, each time the pad is operated, a note event is read out from a memory, a previous tone that has been generated is muted and, at the same time, a next tone for the note event read out is immediately generated so that a legato-like performance can be performed. If desired, a mute switch is operated to mute a previous tone that is being generated so that a staccato like performance is performed. In the second melody mode, the base mode, the first chord mode and the second chord mode, performance data for note events is successively and continuously read out from a memory.
