About Zones
Zones are the independent regions of the keyboard that make up a Multi.
A Multi has 4-16 Zones, each one having its own Program, controller assignments, and
MIDI transmit channel. Zones can be mutually exclusive regions of the keyboard, or they
can overlap. A Zone can also be configured to control an external sound module or computer
software through a MIDI or USB cable.
Muting Zones
Pressing a Zone button will mute or unmute the Zone.
An active/unmuted Zone button has a lit green LED. The LED of an inactive/muted Zone
button is not lit.
