摘要:
A musical tone data compensation apparatus which detects chord components in a performance data stored in accordance with operation of a keyboard and modifies touch data of each tone composing a chord. New touch data are generated by compression or expansion of each difference in touch data with referring to a representative touch data in a block of chord tones, so that emphasis or smoothness is given to a sequence of chords.

An auto-accompaniment apparatus for an electronic musical instrument which includes an accompaniment pattern storage means and chord progression pattern storage means. These accompaniment pattern and chord progression pattern are programmed in the storage means for each type of rhythms. Accompaniment pattern data and the chord progression pattern data are read out from the storage means in response to selection of rhythm. A modifier modifies accompaniment notes in the accompaniment pattern data in accordance with programmed chord name in the chord progression pattern data. A tone generator generates accompaniment tones on the basis of the modified accompaniment notes.
摘要:
An apparatus for producing a chord progression by connecting or chaining chord patterns. In a preferred embodiment, the apparatus includes as a source of musical knowledge, a database of musical structure of various music pieces and a database of chord patterns. In operation, from the musical structure database, a multi-leveled structural feature of a music piece is selected and determined level by level, either automatically, semi-automatically, or manually, through a dialogue conducted between the apparatus and the user. Thereafter, chord patterns are chosen one at a time from the chord pattern database in a similar dialogue manner. A concatenating module controls the concatenation of the chosen chord patterns to be commensurate with the characteristic musical structure previously determined, thereby to provide a chord progression with musicality, naturalness and well-balanced unity and variety. The produced chord progression may be utilized as a musical material from which an automatic composer synthesizes a melody of a music piece.

Root and type of a chord are discriminated at discriminators in accordance with the operation status on a fingerboard. The chord is designated according to a simplified fingering rule predetermined on the fingerboard so as to designate the chord. An automatic accompaniment or a manual play is performed according to the discriminated chord obtained at chord discriminating device.

For use in or with an electronic musical instrument, an automatic accompaniment apparatus has a keyboard, a chord detector detecting a chord played on the keyboard, a judging circuit judging chord establishment of the detector chord, and a chord accompaniment tone generator producing, in accordance with an automatic rhythm pattern, chord tones for the detected chord when chord establishment is judged. This apparatus further comprises a tone generator for producing the tones of arbitrarily depressed keys when chord establishment is not judged. Thus, automatic accompaniment and manual performance are automatically selected according to the state of key depressions.
摘要:
The accompaniment apparatus for an electronic musical instrument comprises an accompaniment segment memory storing data representing a plurality of accompaniment segments which form a plurality of mutually different accompaniment patterns of predetermined lengths, and an alignment sequence memory storing, separately from the above, the orders with which these accompaniment segments are to be aligned sequentially. The data of these orders of alignment of segments are read out one after another, on the basis of which the accompaniment segments derived from the data of the segment memory are aligned one after another sequentially at a given tempo. This operation materializes the automatic accompaniment of any substantial length such as one whole piece of music, and allows the segment memory to have a capacity much smaller as compared to the case in which accompaniment patterns for the whole length of music have to be stored without skipping these segments of the same pattern.
摘要:
An automatic performing apparatus for use in an electronic musical instrument stores chord name data and chord generation timing data to carry out an automatic chord performance. In spite of frequent variations of a chord during the progression of a music piece, repetitive storage of a same chord name data is not required so that the amount of stored data can be reduced, allowing utilization of a memory of a small capacity.
摘要:
A plurality of channels for generating musical tones are provided in LSI chips. A CPU allots a performance mode selected by select switches to the channel or channels. The melody sounds or accompaniment allotted to the channels are generated by a time divisional processing under control of the CPU. The generated sounds are sounded through a loudspeaker, after being subjected to processing by a mixing circuit.
摘要:
An electronic musical instrument which produces counter melody automatically selects one from among chord constituting tones in a predetermined priority order and produces a tone of the same note as the selected tone as a counter melody tone. This electronic musical instrument further comprises a chord type detector for detecting a chord type of a performed chord besides a chord designation detector for detecting the fact that the chord has been designated, a counter melody tone determining circuit for selecting one from among the chord constituting tones and sound system for producing the counter melody tone. The predetermined priority order is determined in accordance with the detected chord type. This dependence on chord type make it possible to produce a counter melody tone which is more rich in music.
