SCENE [1] – [5], [RECALL] keys
Used to recall previously stored Scenes in the unit. When
pressing one of the [1] – [5] keys, the key flashes for
about 10 seconds. (If a Scene corresponding to the key is
not stored, the key doesn’t flash.) When pressing the
[RECALL] key while one of the [1] – [5] keys are flashing,
the Scene is recalled, and the key is lit continuously. Use
the MMP1 Editor to store Scenes.

You can set the [1] key as the all mute key. For details, refer to the
MMP1 Operation Manual.
