    • 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.

    • In order to accurately simulate the sounding system of the stringed instrument such as the violin and cello, an electronic musical instrument provides a performance unit such as a keyboard and a multi-channel sound source unit. As the sound source unit, there is provided a plurality of string sound generating circuits, each corresponding to each of plural strings provided in the stringed instrument, each of which forms a musical tone waveform signal having a different tone color. When performance information is created by operating the performance unit, one of the string sound generating circuits and its fingering position is selected on the basis of the preceding tone-generation assignment state, and then tone-generation corresponding to the created performance information is assigned to the selected circuit. Normally, plural musical tones can be sounded simultaneously in the stringed instrument. However, due to the restriction of the performance which must be inevitably occurred when playing the actual stringed instrument, there is established a restriction condition for the simultaneous tone-generation operation.
    • 为了准确地模拟诸如小提琴和大提琴的弦乐器的发声系统,电子乐器提供诸如键盘和多声道声源单元的演奏单元。 作为声源单元,设置有多个弦声发生电路,每个对应于弦乐器中设置的多个弦中的每一个,每个弦形声产生电路形成具有不同音色的乐音波形信号。 当通过操作性能单元创建性能信息时,基于前面的音调生成分配状态来选择字符串声音产生电路和其指法位置中的一个,然后将与创建的演奏信息对应的音调生成分配给 所选电路。 通常,弦乐器中可以同时发出多个乐音。 然而,由于在播放实际弦乐器时不可避免地发生的性能的限制,因此建立了同时发音操作的限制条件。

    • A lead tone is generated on the basis of an input tone signal. Meanwhile, a specific pitch of the input tone signal is sequentially detected, from which is detected a normalized pitch corresponding to any one of the musical pitch names. Then, difference information is obtained which pertains to a difference between the specific pitch and the normalized pitch, and a pitch having a given pitch interval from the normalized pitch is determined as a target pitch of a tone signal to be generated. Then, a harmony tone is generated which has a pitch obtained by modulating the target pitch in accordance with the difference information.
    • 基于输入音调信号产生引导音。 同时,顺序地检测输入音调信号的特定间距,从中检测到与音调音调名称中的任何一个对应的标准化音高。 然后,获得与特定音调和标准化音调之间的差异有关的差异信息,并且将从归一化音高起始的具有给定音调间隔的音高确定为要生成的乐音信号的目标音高。 然后,产生具有根据差异信息调制目标间距而获得的音调的和声音。
