Abstract: When a harmony function is on state, a generator determines a chord based on one or more notes of depressed keys in a chord kea area, automatically generates one or more additional notes having pitches which harmonizes the pitch of the note of the depressed key in a performance key area according to the determined chord, and inputs the “note of the pressed key in the performance key area+additional notes” to an assignment controller. The assignment controller assigns plural parts (timbres) to the inputted notes, and sounds the notes in timbres of the plural parts according to the assignment. That is, tone generation assignment process is performed regarding not only notes according to performance operation by a user but also automatically generated additional notes.

Abstract: A fluorescence image acquisition method including: irradiating an eyeground with a short-pulse beam of light for exciting a fluorescent dye; setting the time point of emission of the light as a reference, measuring the intensities of luminescence of the fluorescent dye at two different times which are predetermined periods of time after the reference, determining the ratio between the intensities of luminescence at the two different times, and detecting the intensity of luminescence of the fluorescent dye having marked a target by using the ratio; and generating a fluorescence image of the fluorescent dye having marked the target, based on the results of detection by the detecting step.

Abstract: On the basis of performance event information, at least two notes to be sounded in succession or in an overlapping relation to each other are detected, and a tone pitch difference between the detected at least two notes is detected. Tone pitch difference limitation ranges are set in corresponding relation to various rendition styles. Rendition style to be imparted to the notes to be sounded in succession or in an overlapping relation is designated, and a comparison is made between a tone pitch difference limitation range corresponding to the designated rendition style and the detected tone pitch difference, so as determine whether the designated rendition style is applicable or not. In this way, whether the designated rendition style is to be applied or not is automatically controlled in accordance with the tone pitch difference of the at least two notes to be imparted with the rendition style.

Abstract: A dynamic musical system performs a desired musical operation. A plurality of processing units are linked altogether to constitute a network which can distribute therethrough information associated to the musical operation. Each processing unit operates to process the distributed information by a given throughput and can be connected to an external device associated to the musical operation so as to control the same. A master processing unit is selected in the network for checking a characteristic profile of each slave processing unit at least in terms of the throughput thereof and the external device if connected thereto. The master processing unit further allocates adequate jobs to the respective slave processing units according to their characteristic profiles so that all the processing units cooperatively carry out the allocated jobs by either of processing the distributed information and controlling the external device to thereby perform the desired musical operation altogether.

Abstract: An electronic musical instrument has a waveform memory and a tone generator. The waveform memory has a plurality of storage areas, each of which is capable of storing a fixed bit-width data. In the case where the bit-width of the waveform data corresponding to a musical tone waveform is different from the bit-width of the data which can be stored in each storage area, the whole waveform data corresponding to the musical tone waveform are stored in the waveform memory so as not to allow the generation of empty areas which store no data. The waveform data may be divided if necessary and the divided parts of the waveform data are stored in some storage areas of the waveform memory.

Abstract: Reading of a waveform memory is controlled and one of different processing is performed depending upon which of a first mode and a second mode has been designated. When the first mode has been designated, an interpolation operation is performed on the basis of plural sample value data read from the waveform memory by using a predetermined number of processing time slots and a resulting one waveform sample value data is produced. When the second mode, has been designated, a processing for producing one waveform sample value data is performed on the basis of one sample value data read from the waveform memory by using one processing time slot. By using a predetermined plural number of processing time slots, one waveform sample value data produced with a high accuracy in the first mode whereas plural waveform sample value data are produced in the second mode whereby generation of a waveform can be performed efficiently by properly utilizing the mode.
