Quartz Composer Interpolation Tool Programming for Slideshows (Question)

<p>Has anybody used Quartz Composer for building screen saver slideshows?</p>

<p>I am trying to imitate the example provided with the Mac OS X, but I have a question about one of the interpolation tools. There is one, in the templates that show how the screensaver slideshows are built; but one interpolation tool has a connection for "Patch Time". I can find no adjustments through the Inspector in the Quartz Composer Editor that will allow me to create this part.</p>

<p>How is this created? Is it through some form of code available somehow else? Any guidance would be appreciated, as the manual is thin on the specifics; I am learning through part-by-part imitation of the pieces. Thanks. J.</p><div>[ATTACH=full]429417[/ATTACH]</div>

<p>Also, any help on the simplest of mechanics of linking between layers of the macros would be helpful. Thanks.</p>
