摘要： Key information designating a key for a tune to be composed and chord information designating chords for respective chord spans to constitute a chord progression for the tune are inputted to a melody generating apparatus. In the chord span to which a diatonic chord such as C major chord is designated, melody notes are generated using the scale notes of the inputted key, while in the chord span to which a nondiatonic chord such as DbM7 chord is designated, an available note scale is determined based on the key information and the chord information, and then melody notes are generated using the notes such as Ab Bb of the available note scale. As the notes which are neither the scale notes of the key nor the chord tones may be employed for a melody, the generated melody will have musical naturalness and fits the nondiatonic chords also.
摘要翻译：指定要组合的曲调的键的键信息和用于各个和弦的和弦的和弦信息构成用于乐曲的和弦进行的和弦信息被输入到旋律产生装置。在指定了C主弦的全音阶和弦的和弦频段中，使用输入的键的缩放音符产生旋律音符，而在被指定了非平衡弦如DbM7和弦的弦弦中，可用音符根据键信息和和弦信息确定音阶，然后使用可用音符刻度的Ab Bb等音符生成旋律音符。由于既不是音调的音符也不能用于和弦音调，所产生的旋律将具有音乐自然性并且也适合于非音节和弦。

摘要： In an automatic arrangement apparatus having an accompaniment information memory for memorizing an accompaniment pattern, a specific basic part such as a melody part for arrangement of a musical tune, a chord progression and an arrangement condition are applied to select an accompaniment pattern conformed with the arrangement condition from the accompaniment information memory thereby to produce musical information in the form of a pattern sequence of plural parts relative to the basic part, and the pattern sequence of the plural parts is converted in tone pitch in accordance with the chord progression. In the automatic arrangement apparatus, a tone resulting in an inappropriate tone pitch difference for the arrangement of the musical tune is prohibited under a first prohibition rule related to a relationship between the plural pares, and a tone resulting in an inappropriate chord progression for the arrangement of the musical tune is prohibited under a second prohibition rule related to the chord progression. The musical information is corrected to appropriate musical information for the arrangement of the musical tune if the tone prohibited under the prohibition rules is included therein.

摘要： In a pattern memory are stored plural performance patterns, each of which has one or more measures. Plural ones of the performance patterns are optionally selected and read out from the pattern memory, so as to make a music piece made up of time-series combinations of the selected performance patterns. The thus-made music piece is stored into a song memory. A suitable device such as a switch or a detector or a suitable process is employed to instruct to make a music piece in auftakt form. For this purpose, such a method may be employed, for instance, where it is detected that the melody part is in the form of an auftakt music piece, and in response to this detection, it is automatically instructed that the music piece made up of combinations of the performance patters should also be made in auftakt form. In accordance with this instruction, a part of a certain one-measure (last-measure, for example) performance pattern is read out from the pattern memory, and the read-out part of the one-measure performance pattern is added as an auftakt pattern to the beginning of the music piece to be made.

摘要： In an automatic arrangement apparatus, a melody of a part of an original musical tune is memorized in a melody memory (4), chord data of the original musical tune is memorized in a chord progression memory (5), and a rhythm pattern in a rhythm pattern memory (12) is selected in accordance with the style and composition of the original musical tune. At a timing of a note code of the selected rhythm pattern, a top-note, an additional tone, a bass part and a drum part are produced. The top-note is produced by referring to a top-note table stored in a top-note table memory (15) and corresponds with the chord. The additional tone is produced in accordance with the top-note and the chord on a basis of a voicing table stored in a voicing table memory (16). The top-note and additional tone can be selected at a continuous two-tone pair.

摘要： In order to simulate sounds of an acoustic musical instrument such as a bowed stringed instrument, an electronic musical instrument employs a musical tone control apparatus which at least contains an operating device and a detecting circuit. Herein, when operating the operating device which can be operated in a two-dimensional area, the detecting circuit detects operation information corresponding to an operating position or an operating displacement of the operating device. Then, velocity information is generated based on the operation information. Thereafter, a musical tone is generated in response to a musical characteristic corresponding to the velocity information under a condition where the operating device is now operating. Preferably, the operating device is configured by a digitizer on which surface an electronic pen is moved two-dimensionally by the performer. Thus, it is possible to impart the varied performance expression to the musical tone to be generated.

摘要： A digital oscillator generates a basic pulse having a period which is a predetermined large number of times of a clock pulse period. During the basic pulse period are allotted a predetermined small number of time slots defining submultiple frequency channels. There is provided a shift register having the channel number of stages, each stage being assigned to each channel. The contents of the respective stages are changed at respectively different periods which are multiples of the basic pulse period. The contents are taken out timewise-serially, one at a time, stage by stage, and superimposed on the basic pulse to constitute a time-division-multiplexed wave data signal. The delivered signal is demultiplexed to form individual waves having respectively different frequencies which are submultiple-related to the frequency of the basic pulse. This generator is very suitable for electronic musical instruments, as a single line transmits plural wave data.
