Actually, from the way E-Prime thinks, whether it's a SoundOut or a
Slide is critical.  Basically, you can have only one object in any given
experiment with a given name, even if they're different types of
objects.  However, that object can occur in many different places (e.g.,
different procedures) in the experiment.  Therefore, if you're looking
for maximum flexibility, I'd suggest that you make a Slide as your
single stimulus object (and name it Stimulus), create a bunch of
different states for it, and use some inline code to manipulate
Stimulus.ActiveState to taste.  You can then drag that Stimulus object
and the attendant inline code to different procs as much as is necessary
to duplicate it.
