The live view makes it easier to perform a live arrangement of your tracks. While it's also possible to perform in track view, live view has advantages, as explained below. To display the live view, use the View menu's Live command.
Live view features two lists. The left list contains your presets, and the right list contains your tracks and parts. In live view, tracks that belong to a part are hidden; the part's name is listed as a substitute for its member tracks. A part's position in live view is determined by the position of its first member track in track view.
In the track list, muted items are orange, and unmuted items are green. To toggle an item from muted to unmuted or vice versa, left-click it. To mute an item regardless of its current state, left-click it while pressing the Ctrl key.
Items can also be selected via the right mouse button, and then toggled or muted all at once via the left mouse button, in a two-stage process, similarly to the track mutes. This lets you prepare a multi-track transition and then execute it, using only one hand. Selected items are highlighted using dark text on a light background. To toggle the selection of an item, right-click it. To toggle the selection of a group of adjacent items, right-click the group's first item, and then while keeping the right mouse button pressed, drag the pointer to the group's last item. To deselect all items, right-click in the area to the right of the track list. If a selection exists, left-clicking anywhere within the view toggles or mutes the selected items, depending on whether the Ctrl key is down. The selected items can also be soloed, using the solo button at the top of the view.
The presets list works somewhat differently. To apply a preset, left-click the corresponding item. To select a preset, right-click the corresponding item. If a preset is selected, left-clicking anywhere in the view applies the preset. Only one preset can be applied or selected at a time.
Live view shows a progress bar for each track list item. Each progress bar indicates the current position within the corresponding track or part. If a part's member tracks have different periods, its progress bar corresponds to the longest period.
If your arrangement is complex, you may prefer to record each section separately, instead of trying to get all the sections right in one take. To append a new section, move the song position to the end of the last completed section before you start recording. Your live arrangement can be approximate, because you can refine its transitions later in song view.
It's a good idea to record your rehearsals, in case there's a happy accident. You may want to use the Always Record option, so that you can't accidentally fail to record a perfect take. In order to further reduce visual clutter, it's recommended to use live view in full screen mode.
