PSR-9000
15. 015:TG1
Chk
Produces the sine wave sequence by changing the sound channels (1ch-64ch) in order from A0 toC6.
Confirm that there is no noise.
After autoscaling is finished, individual keys can be played. (If playing two or more keys simultaneously,
the key pressed first has priority to make a sound.)
When the voice switch is pressed, the tone of the voice will sound.

032:SP MUTE
When the [NEXT/BACK] button is pressed, check that the 1 kHz sine wave tone from the speaker
stops. Press it again and the sound will come back on.
During this test, the external output terminal signal will remain on the entire time.
