This is a device that selects and adjusts the level so as to output from the corresponding output terminal (microphone terminal 31 / effect terminal 33 / music terminal 35 / BGM terminal 37).
[0012]
The MIDI sound source 53 generates an audio signal based on the MIDI data in the karaoke data. The MIDI data includes karaoke data (MIDI data, MPEG audio data, background image data, lyric data, etc.) corresponding to the song number selected by the user, and the karaoke control device (see FIG. 4) has its auxiliary storage device (see FIG. 4). 4 (which is composed of a hard disk or the like), MIDI data is extracted therefrom, and is provided to the MIDI sound source 53.

In the synthesis / processing / adjustment 40, each audio signal (microphone input audio signal, MIDI audio signal, MPEG audio audio signal, BGM signal) generated as described above falls within the one-dot chain line frame in FIG. An exemplary process is performed.
[0015]
For example, level adjustment based on karaoke data is performed on the MPEG audio sound signal generated by the MPEG audio sound source 55, and the MPEG audio sound signal after the level adjustment is combined with the MIDI sound signal generated by the MIDI sound source 53. . The synthesized audio signal is appropriately adjusted in response to a manual operation of an operation key (an operation input key provided on an operation panel of the karaoke control apparatus).
[0016]
The audio signal after the manual adjustment is combined with an audio signal that is input from the BGM terminal, manually adjusted as appropriate, and further adjusted in level based on karaoke data. This composite signal is sent to the select. That is, either one of the synthesized signal and an audio signal input from the BGM terminal and manually adjusted as appropriate is selected by a select controlled based on karaoke data.
[0017]
The synthesized signal is also synthesized with an audio signal based on a microphone input. The sound signal based on the microphone input is input from the terminal 51 and manually adjusted as appropriate, and further processed (effect processing such as echo) based on the karaoke data, and input from the terminal 51 and appropriately adjusted manually. Furthermore, the audio signal is level-adjusted based on karaoke data.

The audio signal after selection by the level adjustment / output decision is output from the microphone terminal 31 / effect terminal 33 / music terminal 35 / BGM terminal 37 or not output. That is, it is output when output is possible, and is not output when output is not possible.
[0020]
This output level setting / output destination terminal switching procedure will be described with reference to FIG.
First, model information is acquired. The model of the connected audio output device (model A / model B / model C) is set in advance by a dip switch of the karaoke control device, for example, and the information is stored in the storage device ( It is assumed that it is held in an auxiliary storage device or the like. The setting is not limited to the DIP switch, and may be set by other operation keys or interactive input on the menu screen.
