When in multi mode, a bar of 12 voice tabs will appear at the top of the voice section of the GUI.

Voice Tab
Click on a voice tab to view it in the main Matrix 12 voice panel.
The currently viewed voice will have a blue tab, the others will be grey.
A tab with a white boarder is part of the currently active Rel Edit Group, see Relative Edit (Multi mode only)
Activity LED
Each tab has a green LED that shows the current output level of that voice. Clicking the LED will disable that voice, turning it red.
Voice Menu
Click the hamburger menu icon to the left of each tab to open the voice menu to access a suite of secondary actions.

- Load - Enters the Voice Load Browser, see more about this below.
- Copy - Copies this voice’s settings into the internal clipboard.
- Copy To All - Copies this voice’s settings immediately onto all other voices in Matrix 12.
- Copy To Zone - Copies this voice’s settings immediately onto all other voices that share the same voice allocation as it.
- Paste Voice - Pastes the voice copied into the internal clipboard. You’ll see the copied voice number here before pasting.
- Lock - Prevents this voice from being edited, or changing when switching patches.
- Disable - Prevents this voice from playing. It will be skipped in the voice allocation cycle.
- Solo - Temporarily disables all other voices and accepts all MIDI input into this voice to be heard individually.
- Make / Current Single - Enables Single mode with this voice as all 12 voices. You’ll see “Current Single” when this voice would be used when changing to single mode via the Single/Multi button anyway, and “Make Single” when it wouldn’t have been.
