摘要： An interactive drum set includes a storage device for storing data representing sounds of a plurality of background music styles, sounds of a plurality of drum beat sequences, and sounds of a plurality of percussion instruments. The drum set also includes a plurality of drum plates for receiving user-directed forces, each of the plurality of drum plates being associated with the data representing sounds of one of the plurality of percussion instruments. A sensor disposed at each of the plurality of drum plates detects the user-directed forces and generates a signal indicative of the user-directed forces. A triggering device operatively connected to each sensor outputs a trigger signal when the signal of the sensor exceeds a threshold value. A user-interface device responsive to user commands supplies signals indicative of a user's selection of at least one background music style and/or at least one drum beat sequence. A controller, responsive to the trigger signal of the triggering device and the signal from the user-interface device, retrieves and outputs data from the storage device representing sounds of at least one background music style, at least one drum beat sequence, and/or one of the plurality of percussion instruments.

摘要： An audio apparatus extracts information of a musical performance from an acoustic signal having a frequency and an amplitude, which time-vary during the musical performance. In the audio apparatus, a filtering device has a plurality of filters which are set with different cutoff frequencies so as to pass different frequency ranges of the acoustic signal. A pitch detecting device is connected to the filtering device for processing the acoustic signal to detect therefrom a pitch. A controlling device operates according to the detected pitch fed back from the pitch detecting device for selecting one of the filters set with one of the different cutoff frequencies adapted to the pitch of the acoustic signal so that the pitch detecting device can detect the pitch based on the acoustic signal filtered by the selected filter. Further, the envelope detecting device has a plurality of envelope followers corresponding to the plurality of the filters. Each envelope follower processes the acoustic signal to extract therefrom an envelope representing a time-variation of the amplitude of the acoustic signal and containing an upward portion and a downward portion such that each envelope follower forms the downward portion by a given slope which matches the frequency range of the corresponding filter.

摘要： In an electronic musical apparatus having an acoustic instrument manually operable to commence an acoustic vibration and a tone generator responsive to the acoustic vibration to generate a musical tone having a pitch corresponding to that of the acoustic vibration, a pitch detecting device utilizes a pickup for picking up the acoustic vibration to convert the same into a waveform signal. Further, a first detector operates according to a fast algorithm for processing the waveform signal so as responsively produce a first output representative of the pitch of the acoustic vibration, and a second detector operates in parallel to the first detector for processing the same waveform signal according to a slow algorithm so as to stably produce a second output representative of the pitch of the acoustic vibration. A selector selectively feeds one of the first output and the second output to the tone generator so that the first detector and the second detector can cooperate to ensure responsive and stable detection of the pitch. An additional detector processes the waveform signal to measure a time interval between a pair of the peaks so as to detect a plucking point. A controller controls the tone generator according to the detected plucking point to change the timbre of the tone generator.

摘要： Analysis data are provided which are indicative of plural components making up an original sound waveform. The analysis data are analyzed to obtain a characteristic concerning a predetermined element, and then data indicative of the obtained characteristic is extracted as a sound or musical parameter. The characteristic corresponding to the extracted musical parameter is removed from the analysis data, and the original sound waveform is represented by a combination of the thus-modified analysis data and the musical parameter. These data are stored in a memory. The user can variably control the musical parameter. A characteristic corresponding to the controlled musical parameter is added to the analysis data. In this manner, a sound waveform is synthesized on the basis of the analysis data to which the controlled characteristic has been added. In such a sound synthesis technique of the analysis type, it is allowed to apply free controls to various sound elements such as a formant and a vibrato.

摘要： An electronic percussion system having the look, feel and response of an acoustic drum is provided by a combination of a drum body shell, conventional drum heads held at adjustable tension across open ends of the shell, and within the interior drum cavity a sound-to-electrical transducer is embedded in layers of rubber foam filler material. The sound energy attenuating characteristics of the foam filler material prevent the transducer from being falsely triggered by ambient sound exterior to the drum, by sympathetic vibrations of the drum, and resists false triggering due to lightly, inadvertently hitting the drum stand. In a bass drum embodiment, the transducer is mounted directly between layers of low density rubber foam, while a snare and tom drum configuration includes a thin sound plate that floats between layers of rubber foam and to which the transducer element is mounted to excite the transducer by capturing sound energy from the striking head while selectively discriminating against other ambient sounds and sympathetic vibration.

摘要： A system and method for detecting, separating and recording the individual voices in a musical composition performed by a plurality of instruments. The electrical waveform signal for the multi-voiced musical composition is fed to a waveform signal converter to convert the waveform signal to a frequency spectrum representation. The frequency spectrum representation is fed to a frequency spectrum comparator where it is compared to predetermined steady-state frequency spectrum representations for a particular musical instrument. Upon detecting the presence of a frequency spectrum representation corresponding to a predetermined steady-state frequency spectrum representation, the detected frequency spectrum representation and measured growth and decay frequency spectrum representations are fed to a waveform envelope comparator and compared to predetermined waveform envelopes, i.e. frequency spectrum representations during the growth, steady-state and decay periods of the waveform signal. Upon detecting the presence of a waveform envelope corresponding to a predetermined waveform envelope, the steady-state and transient properties of the detected frequency spectrum representation are recorded and converted to an electrical waveform signal for output as music data for an individual voice.

摘要： A detecting device for detecting the positions where strings are operated, and an electronic musical instrument using the detecting device, such as an electronic stringed instrument of an electronic keyboard instrument. Wherein each of frets, with which conductive strings are brought into contact, is formed of a two-layer structure of a conductive member and a resistance member provided on the conductive member. Voltage pulses are sequentially applied to either the conductive strings or the conductive members of the frets and a voltage pulse is detected from a conductive member or a string, thus detecting a position in which a string is stopped against the fret.
