Select Project 5

Select the fifth project. There is no way to tell what the fifth project actually is. This is likely to be a hold over from early days of Logic going all the way back to “songs”. MainStage is the preferred tool for having multiple songs available for playback.

Studio One now has a “Live Performance” page built in (2020).

Generally speaking it is a bad idea to work with multiple projects open at once. Far too many problems with Logic can be traced to having multiple projects open at once. Caveat Emptor.

In my current test with multiple projects open at the same time the project number appears to be the position of the project in the Windows menu. Project 1 is the first project, project 5 is the fifth.

  Select Project 18

Nope — I won’t have 18 projects open. Common wisdom is that having more than one project open at a time can lead to project corruption.

This could be a holdover from the early versions of Logic where projects were called “songs”, and people using Logic for playback in peformances would have many songs open, strictly for playback.

The current world has MainStage for playback purposes. A far better tool for backing tracks or, possibly, programmatic audio.

There is no documentation in user manuals for Logic 7, 8, 9, or 10.

  New Project Alternative…

Create a new alternative for a project. You will be asked if you want to save changes before the alternative is created. You now have a starting point for the project to begin changes. You can return to the previous alternative by selecting it from the Project menu.

Sort of like a ‘save as’ without replicating all of the assets and other things. I use alternatives whenever I am working with a live set of music. One alternative for each song.

Use Logic Pro project alternatives and backups — Apple Support

When Show Advanced Tools is selected in the Advanced preferences pane, you can create alternative versions of a project, each with a unique name and different settings. Project alternatives let you save “snapshots” of a project in different states, including different cuts or mixes. They’re saved as part of the project and share the same assets. Alternatives for the current project appear in the File > Project Alternatives submenu.

  Select Next Project

You can have multiple projects open at the same time. Typical advice is to not do this. Which project is “next”? The behavior is not documented anywhere, as well as a lack of documentation describing how projects are numbers — see the ‘Open Project nn’ commands.

Open Logic Pro projects — Apple Support

You can open an existing project to continue working. You can also open several projects simultaneously, allowing you to copy or move data between them, or to compare different versions of a project.
