    • A musical sound generator combines a software processing and a hardware processing. A sub CPU210 generates musical note data based on the musical score data 340. Main CPU110 refers to a sound source file, converts musical note data and generates PCM data. A sound processor 210 converts the musical note data at a sound synthesis circuit 221 to generate PCM data. D/A converter 222 converts the PCM data into analog signals. The speaker 300 receives the signals and emits the sound.
    • 音乐声音发生器结合了软件处理和硬件处理。 子CPU210基于乐谱数据340生成音符数据。主CPU110参照声源文件,转换音符数据并生成PCM数据。 声音处理器210在声音合成电路221处转换音符数据以产生PCM数据。 D / A转换器222将PCM数据转换为模拟信号。 扬声器300接收信号并发出声音。

    • A musical instrument having a signal output function 1 for outputting a given signal in response to a user command, and a mode managing function 2 for managing process modes of an electronic keyboard and compulsorily finishing an arbitrary process mode of the electronic keyboard when the signal is outputted by the signal output function 1, and for changing to a tone color selection mode after the compulsory finish for setting a tone color of the electronic keyboard to a given tone color. Even during each of the process modes, the tone color of the electronic musical instrument can be compulsorily set to a given one.
    • 具有用于响应于用户命令输出给定信号的信号输出功能1的乐器,以及用于管理电子键盘的处理模式并且强制完成电子键盘的任意处理模式的模式管理功能2,当信号为 由信号输出功能1输出,并且在用于将电子键盘的色调设定为给定音色的强制完成之后改变为音色选择模式。 即使在每个处理模式下,电子乐器的色调也可以被强制设定为给定的。
