The control command is not necessarily output at the same time as the start of key operation1, but after a certain period of time has elapsed from the start of key operation.
Alternatively, it may be output when a key operation ends. In such a case, there is a disadvantage that the operator feels uncomfortable because no operation sound is produced when the key operation starts.

音が出力される。In the present invention, prior to this control command, a dedicated operation sound command is transmitted from the head unit 10 to the adjustment device 20 at the start of key operation. When the adjustment device 20 receives this operation sound command, it generates and outputs an operation sound.
An unadjusted operation sound is output from the speaker 30 at the same time as the key operation starts.

る操作音コマンドを受けたときにこれを行う。When receiving an instruction to generate an operation sound from the CPU 22, the DSP 21 generates and outputs a predetermined operation sound. This is the same method as shown in FIG. However, the CPU 22 does not issue an instruction to generate an operation sound upon receiving a control command (it does this upon receiving a preceding operation sound command).
操作音コマンドはキー操作部１３においてキー操作を開

The command in this example is 3 bytes, the first 1 byte (8 bits) is a device code specifying the destination device, the next 1 byte is a command, and the last 1 byte is a control step. In a normal control command, the type of characteristic to be adjusted is indicated by "instruction-1", and the degree of adjustment is indicated by "1-control step". On the other hand, the operation sound command is an instruction L7 for the type of operation sound corresponding to the key.
