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.

Video synchronization based on audio

In a synthesizer, when a function of a tone generation moduleprovided by an external tone generation serveris usable, a tone generator control moduleassigns a necessary number of sound generation channels among sound generation channels of an internal tone generation unitand sound generation channels of the external tone generation module, for sound generation corresponding to MIDI data. When assigning the sound generation channel of the tone generation module, the tone generator control moduletransmits, to the tone generation server, 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 moduleto generate waveform data according to the transmitted MIDI data.

Waveform generating apparatus

A synthesizeris configured such that when a PCis connected thereto, the synthesizeraccepts selection of a tone used for sound generation from among a tone included in an internal tone generation unitand a tone included in a tone generation moduleprovided by the external PC, and causes the PCto enable the function of the tone generation module, downloads an edit operation accepting program corresponding to the tone generation modulefrom a UI control program memoryof the PC, 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, the data being stored in the PC, when the tone included in the tone generation moduleof the PCis selected.

Waveform generating apparatus, sound effect imparting apparatus and musical sound generating apparatus

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.

Audio signal processor with pitch and effect control

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. As another example, reference scale note pitch data may be supplied, instead of the scale note pitch nearest to the detected pitch of the input sound signal being determined in the above-mentioned manner.

Apparatus and method for generating additional sound on the basis of sound signal

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. A harmony voice signal will be produced with a tone pitch determined by the captured performance data and in a voice determined by the voice of the received voice wave signal. The original voice wave signal may be sounded in audible voice, and the performance data may be sounded in audible music.

Apparatus and method for generating harmony tones based on given voice signal and performance data

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.

Music apparatus with pitch shift of input voice dependently on timbre change

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. Each time the pad is operated, the apparatus generates at least a tone for a note event that is read out at a moment of operation of the pad. In the ad-lib mode, different tones for ad-lib performance are assigned to the fret switches. When the pad is operated while any of the fret switches is depressed, at least a tone having a pitch assigned to the fret switch is generated.
