摘要： A tone generating apparatus which comprises a wave memory in which first tone waveform data with a preselected length extracted from an attack portion of a musical tone and second tone waveform data with a preselected length following the first tone waveform data and having a value of zero are stored. A read circuit reads the first tone waveform data only once from the wave memory and subsequently reads the second tone waveform data repeatedly. A tone generator generates a musical tone based on the tone waveform data read out by the read circuit. In reading out tone waveform data from the wave memory, the first tone waveform data is read out first, followed by repetitive reading of only the second tone waveform data.Repetitive reading of the second tone waveform data produces no sound because the contents of the second tone waveform data are zero. Thus, this system performs a function equivalent to tone release effected by reading out a one-shot waveform.

摘要： Header control data for setting various characteristics of an automatic performance tone such as tone color, tone volume, tempo, effect and the like are stored in a header portion of a memory. The header control data are loaded into a buffer register, and various characteristics of an automatic performance tone to be generated are established on the basis of the header control data stored in the buffer register. In response to activation of a changing operator, the header control data in the buffer register are changed and a hence various characteristics of the automatic performance tone to be generated are changed. When the data in the buffer register is changed during an automatic performance, the header control data stored in the memory is changed in correspondence to the change. Therefore, during an automatic performance, various characteristics of the automatic performance tone can freely be changed while listening to the generated automatic performance tone, and also the header control data stored into the header portion of the memory can be automatically rewritten in correspondence to such change.

摘要： A polyphonic breath controlled electronic musical instrument includes a hand held breath sensor unit having a plurality of bidirectional air flow sensing passageways for detecting sucking or blowing action of the performer in a manner similar to a conventional acoustic harmonica. The breath sensor unit further includes pressure sensing transducers on the surface thereof, adapted to sense lip pressure and finger pressure of the performer, as well as a plurality of switches activated by the fingers of the performer holding the breath sensor unit. A microphone configured in the breath sensor unit picks up the vocal sounds of the performer. A thumb wheel controller is provided on the sensor unit to allow a control of tone parameters, such as volume, by the thumb of the performer. The signals from the sensors and switches on the sensor unit are provided to a remote electronic control unit which converts the analog sensor signals and on/off switch signals to MIDI control data in response to programs set by the performer. The performer may set various combinations of tone effects which may be varied in the performance by the performer activating the switches and pressure sensors. A tone generator receives the MIDI control signals and provides musical tones in response thereto. A conventional acoustic harmonica may be accurately emulated in addition to providing a number of other digital musical effects.

摘要： A music interpreter apparatus automatically interprets a notational music composition (written or printed music), which is abstract and incomplete to some extent, to provide its performance realization information which is specific and complete. The apparatus includes a score memory, an interpreter and a performance memory. The score memory stores a coded music notational symbol string representing a written music composition. The interpreter reads and interprets the coded music notational string based on an artificial intelligence simulating knowledge and experience of a human music interpreter or performer to provide a performance symbol string specifying the performance realization and containing played pitch, note-on time, duration and loudness parameters of specified values with respect to each note in the music composition. The resultant performance symbol string is stored into the performance memory.

摘要： Muting of an electric guitar is accomplished by sensing depression of a string by the player during playing, and deactivating an electrical muting circuit in response to said depression. To sense string depression, each electrically-conductive string is supplied with a voltage with respect to the metal frets of the guitar, so that upon depression of any string a current flows through that string to a corresponding transistor which turns off the normal muting of that string; upon release of the string, the current stops and the muting resumes. The muting is preferably accomplished for each string by a corresponding respective FET, normally turned on to short-circuit to ground the audio signal from that string. Resistance-capacitance circuits are provided to control how fast the muting is turned on and off.

摘要： A pitch is extracted from an input waveform signal, and a musical tone having a corresponding tone pitch is generated. In this case, a signal intensity at the leading edge of the input waveform signal is detected to determine a tone volume of the musical tone. A change degree of the signal intensity at the leading edge of the input waveform signal is detected to determine a timbre of the musical tone. As a result, the tone volume and the timbre of the output musical tone can be independently controlled in accordance with a music performance manner, and an improvement of a performance effect is expected.

摘要： A plurality of waveshapes of different characteristics are stored in a waveshape memory among which a waveshape to be read out is selected in accordance with a selected tone color or elapse of time and data of the selected waveshape is read out. At least one waveshape among the waveshapes stored in the waveshape memory is coded in a coding form different from one used for the other waveshapes. For matching characteristics of each individual waveshape, waveshapes are coded according to respectively suitable coding forms such, for example, that one waveshape is coded according to the pulse code modulation system, another waveshape according to the differential pulse code modulation system and still another waveshape according to the delta modulation system. The waveshape data read out from the waveshape memory is converted in its code to a predetermined common coding form (e.g. PCM). By differring the coding form of waveshapes stored in the waveshape memory, reduction in the memory capacity and improved resolution in reproduced waveshapes matching characteristics of individual waveshapes can be achieved.
