Abstract: In an automatic performing system, when the track is changed to one having a different loop bar number, the bar to be reproduced next is easily determined by first dividing the number of bars accumulated from the start of accompaniment by the loop bar number stored in the sequence track. Based on the remainder resulting from the division, the number of beats is determined and the present pointer is set. In the automatic performing system, by comparing the data at the next address with the part designation data, it is determined whether the read out data belongs to the designated part or not. Therefore, the accompaniment data corresponding to the designated part data can be read out and reproduced.

Abstract: An automatic performance apparatus extracts characteristic data indicating individuality of performance of a player from performance data, compensates for score data exhibiting no individuality by the characteristic data, and executes an automatic performance using the compensated data. The apparatus includes a characteristic extraction unit and a characteristic regeneration unit. The characteristic extraction unit extracts characteristic data on the basis of a correlation between performance data and score data, and stores the extracted data in a characteristic data storage unit. The characteristic data is extracted with regard to styles of performance in association with notes, signs attached to the notes, dynamic marks, tempo marks, the general flow of music, and the like with reference to score data exhibiting no individuality. The characteristic regeneration unit compensates for arbitrary score data with the stored characteristic data to generate performance data.

Abstract: A preferential order of channel vacating is determined according to a musical character of musical tones having assigned channels, thus permitting a channel assignment which does not depart from the harmony of the musical tone. The greater the number of tones which are equivalent in musical character, the more readily channels can be vacated for new tones, and tones with fewer equivalent tones in musical character may remain assigned. The channel selection may also be limited for low envelope level tones.

Abstract: Disclosed are a chord detecting/storing apparatus and an accompaniment information processing apparatus. The chord detecting/storing apparatus designates tones consisting of a chord on a keyboard, and extracts one of the designated notes. Based on the extracted note, the apparatus prepares a row of note bits excluding at least one note. Using this note bit row as an address, the apparatus searches for a chord table in advance where chord information is stored to correspond to each pattern for a row of note bits, and reads out searched chord information to detect a chord.The accompaniment information processing apparatus detects component tones of a chord when the chord is designated from the keyboard, and generates chord information. The accompaniment information processing apparatus produces specific tone information in association with the generated chord information and correlates the specific tone information with the chord information before storing both information items.

Abstract: A waveform data storing unit stores waveform data only at steps midway among a top zero level step and originally sampled steps at every sampling period from the top zero level step. An output means is included for outputting the waveform data at a moment staggered from another moment, at which the waveform data at the top zero level step and the originally sampled steps are ordinarily read out, by a period of time corresponding to half a step. The occurrence of a difference in phase of the read-out waveform is prevented without the need of a data correction unit. The waveform data storing unit stores midway-step data which are averages of waveform data at adjoining originally sampled steps and difference data representing the difference between the waveform data at the originally sampled steps and the midway-step data. A fine waveform can therefore be obtained while using a smaller quantity of data.
