The Holding Tank is on the left side of the Mx. Voice window. It’s a staging area where you can collect songs for a show. It operates in two modes: Storage for individual access, or Playlist for automatic sequential playback.

Use the two mode buttons in the holding tank header to switch between modes.
| Mode | Behavior |
|---|---|
| Storage (default) | Songs are played individually. Click a song to select it, double-click to play. Playback stops at the end of each song. |
| Playlist | Songs play automatically in sequence. When one song ends, the next starts. A speaker icon indicates the currently playing track. |
Songs can be reordered by dragging them within the holding tank list.
Like hotkeys, the holding tank has 5 tabs for organizing different groups of songs. Each tab maintains its own song list independently.
Save and load holding tank lists as .hld files. This is useful for preparing setlists in advance.
Right-click on any song in the holding tank to see a context menu with these options:
| Shortcut | Action |
|---|---|
| Shift+Tab | Add selected song to the holding tank |
| Delete | Remove selected song from the holding tank |
