How do I create Audio Objects in Logic?

If for some reason your default song doesn’t contain all the objects you need, there are various ways to create a new Audio Object.
1. Clumsy method. Open the Audio Mixer, and in the window’s View menu, uncheck “Protect Cabling/Positions”. Then from the window’s New menu, pick “Audio Object”. A tiny object will be added in the window. With the object selected, you’ll see its parameter pane on the left-hand side of the window, containing a.o. a “Cha” parameter. Click to the right of “Cha” and a menu will pop up from which you can pick the type of object you’d like to add to your mixer. Finally double-click the object itself, to have it expand to a full-blown channel strip.
2. Clever method. Open the Audio Mixer, and in the window’s View menu, uncheck “Protect Cabling/Positions”. While pressing Option [Ctrl], click on the name of an existing Audio Object (i.e. right below the channel strip), and drag to create a copy of the selected Object. With the new Object selected, you’ll see its parameter pane on the left-hand side of the window, containing a.o. a “Cha” parameter. Click to the right of “Cha” and a menu will pop up from which you can pick the type of Object you’d like to change this one into.
3. For bulk-creation of Audio Objects: press Option [Ctrl] while picking ‘New’ from the File menu. Logic creates a new song which contains all possible Audio Objects. Go to the Audio Mixer, ‘select all’ and ‘copy’. Close the song (don’t save). If you still had your Autoload open, go to the Audio Mixer, ‘select all’, ‘delete’ (backspace – don’t use ‘Cut’ since we still need the clipboard contents we copied there earlier), and finally ‘paste’ all Audio Objects. In the window’s View menu, uncheck “Protect Cabling/Positions” if needed before hitting backspace (or just tell Logic to go ahead and delete everything if it asks you). If you had closed your Autoload prior to creating the new song, just hit Command [Ctrl]-N after closing the new song, to have Logic create a fresh copy of your Autoload. Then proceed as described. And… of course you shouldn’t forget to save your new Autoload.
Note that recent versions of Logic (we’re now at 5.5) seem to handle simultaneously opened songs somewhat unreliably. You might therefore choose to close all opened songs before you let Logic create the “new song with all objects”.
Also note that the number of Track Objects which Logic will create depends on the settings you made in the “Audio Hardware & Drivers” dialog (in the Audio menu): the “Max. Number of Audio Tracks” setting is the thing you’re looking for.
