The [MASTER INSERT/(WAKE UP)] button sometimes blinks even though I'm not using [MASTER INSERT]. Why?

If the unit is displaying the [UTILITY] screen, the button will blink even if [MASTER INSERT] isn't in use.

In this case, the [MASTER INSERT] function can't be turned on or off.

To use [MASTER INSERT], press the [TAP] button to exit the [UTILITY] screen.
