摘要： A performance data generation apparatus generates performance data for controlling the tone generation condition of a tone to be generated based on a string vibration signal obtained from the string vibration of a stringed instrument. The performance data generation apparatus includes an operation member for selecting a predetermined performance operation mode and a control device responsive to the operation member. When the predetermined performance operation mode is selected by operating the operation member, the control device does not output note-on data or note-off data among performance data that is generated based on the string vibration signal, and outputs specified performance data other than the note-on data and the note-off data.

摘要： A karaoke apparatus is provided with a pickup device that collects a singing voice sound to convert the same into a corresponding vocal signal. Further, a music generator device generates a music signal representative of a karaoke accompaniment sound which is selected to accompany the singing voice sound. A harmony generator device generates a harmony signal representative of a harmony chorus sound which is made consonant with the singing voice sound. A first processor device processes the vocal signal to impart an effect to the collected singing voice sound. A second processor device processes the harmony signal separately from the vocal signal to impart another effect to the harmony chorus sound independently from the singing voice sound. A sound device amplifies the processed vocal signal, the processed harmony signal and the generated music signal so as to sound the singing voice sound, the harmony chorus sound and the karaoke accompaniment sound concurrently with each other.

摘要： In a piano which is enabled to provide performance using electronic sound source as well as normal piano play, the proposed piano is such a piano where there is no difference of balance between the normal piano play and the play using electronic sound source. When key is moved in an electronic sound source mode, CPU detects a number n of the key (S110), detects a time lag .DELTA. T between the timings at which blockage is caused between light emitting elements and light receiving elements of both key sensors (S120), and calculates a velocity V according to the time lag .DELTA. T (S130). Then, performance data is prepared according to these key depression information, at the performance data preparation routine (S140), and a delay time Td corresponding to the velocity V is determined by using a delay time determination table (S150). Subsequently, it is determined whether the delay time Td has elapsed (S160). When it has elapsed, the performance data is outputted to the electronic sound source (S170). As a result, sound is created, with the delay time Td, according to the key depression intensity as an interval after the key depression.

摘要： An electronic music system has an input device, one or more computer storage media, a rhythm generator, a pitch selector, and a sound generator. The input device generates rhythm-related input signals and pitch-related input signals in response to manipulations of the input device by a user attempting to create and play a solo. The computer storage media have a plurality of user-selectable musical accompaniment tracks over which the user can create and play the solo and a plurality of rhythm blocks wherein each rhythm block defines, for at least one note, at least a time at which the note should be played. The computer storage media also store at least a portion of the solo created by the user over a predetermined time interval in the immediate past. The rhythm generator receives the rhythm-related input signals from the input device, selects one of the rhythm blocks from the computer storage media based on the rhythm-related input signals, and outputs an instruction to play the note at the time defined by the selected rhythm block. The pitch selector receives the pitch-related input signals from the input device and selects an appropriate pitch based on the pitch-related input signals, the user-selected musical accompaniment track, and the stored solo information. The pitch selector then outputs that appropriate pitch. The sound generator receives instructions from the rhythm generator, pitches from the pitch selector, and the user-selected musical accompaniment track and generates an audio signal representative of the user-created solo and the accompaniment track.

摘要： A detector is provided which generates detection signal that represents a value varying in response to the movement of a key operated on a keyboard. The key operating style employed for the operated key is reflected in subtle, dynamic action occurring in connection with the operated key during depression of the key. For instance, if the key operating style for the operated key has more staccato factor or characteristic, then the action of the operated key will present nonlinear characteristics relatively remarkably. Thus, the key operating style for the operated key can be determined on the basis of time-varying values of the detection signal, and by controlling tone depending on the determined key operating style, it is possible to achieve good-quality tone control, well reflecting subtle differences in key operating styles such as staccato, tenuto and the like, which is difficult to achieve with the conventional touch control techniques.
