    • There are provided a device for sampling a tone signal applied from outside, a built-in tone source, responsive to tone pitch information, a tone signal having tone pitch corresponding to the tone pitch of the tone pitch information, a memory capable of both writing and reading for storing waveform sampled data and a control circuit for selectively writing a tone signal sampled or a tone signal generated from the built-in tone source. The waveform sampled data in the memory is read out in accordance with designated tone pitch. A circuit is provided which, when input of a tone signal sampled has not been detected for a predetermined period, causes a tone signal generated from the built-in tone source and written in the memory. There is also provided a circuit which generates a tone of a reference pitch when a predetermined switch operation has been made with the tuning operation. There is also provided a circuit for selecting whether pitch adjustment should be made in both a sample tone source having a memory storing a tone signal sampled and the built-in tone source or the pitch adjustment should be made only in the sampled tone source. There are provided a circuit for generating pattern data designating tone sounding timing and tone pitch in accordance with a rhythm pattern and a circuit for performing selection as is whether the sampled tone source be driven in accordance with this pattern data or in accordance with a key depression.
    • 提供了一种用于对从外部施加的音调信号进行采样的装置,响应于音调音调信息的内置音源,具有与音调音调信息的音调音调相对应的音调音调的音调信号,能够进行写入的存储器 以及用于存储波形采样数据的读取和用于选择性地写入从内置音源产生的采样的音调信号或音调信号的控制电路。 根据指定的音调音调读出存储器中的波形采样数据。 提供一种电路,当在预定时间段内没有检测到采样的音调信号的输入时,产生从内置音源产生并写入存储器的音调信号。 还提供了一种在调谐操作进行了预定的开关操作时产生基准音调的音调的电路。 还提供了一种电路,用于选择是否应该在具有存储采样的音调信号的存储器和内置音调源的采样音源中进行音调调整,或者仅在采样音源中进行音调调整。 提供了一种用于根据节奏模式产生指定音调定时和音调音调的模式数据的电路,以及用于根据该模式数据或根据键按压来执行选择的电路。 。
