Voices can be allocated to one of six zones. Allocation is done in the mixer section above Zone Control.

Zones dictate the range of notes a voice responds to, as well as how those notes will be assigned voices.

Zones also have helpful shortcuts to copy/paste and edit voices within a zone as a group.

Zone Menu

Click the hamburger icon in the Zone’s header bar to access a list of secondary actions.

• Copy Zone - Copy this zone’s range and arp settings into the internal clipboard.
• Paste - Pastes the above copy.
• Lock - Prevents this zone from being edited, or changed when loading patches
• Disable - Prevents this zone, and it’s associated voices, from play.
• Solo - Temporarily disables all other zones, and increases the solo’d zone’s note range to cover all inputs.

Zone Activity LED

The green LED in the header bar flashes whenever it sends a note to a voice. Clicking this LED will also disable the zone. The LED will turn red to show this.

Voice Assignment Mode

This setting selects how incoming notes are assigned to voices within the zone.

• Rotate - new notes are assigned to the next available voice in numerical order. The classic Oberheim way.
• Reset - new notes are assign to the lowest available voice in numerical order.
• Assign - notes remember the last voice that they used and will use that voice again if available. If it’s not available, they’ll rotate. The classic Prophet way.
• Unison - all voices are assigned to every new note, firing all at once.

<aside> ⚠️

Matrix 12 actually had 3 different unison modes, we’ve chosen only to include Unison Last, where all new notes steal the voices. Unison High and Unison Low have not been included as we have found them to be unpopular in software instruments.
