Don't Hear Plug-in Effect In Logic Express 7, Learning Logic Express 7 problem Options

[alexbutterfield]

I am teaching myself Logic Express 7 using Martin Sitter's Apple Pro Training Book. I am in the first lesson and have gotten to the section about inserting plug-ins. I can insert and open the plug-in for Modulation Delay/ Slow Panning Chorus on the suggested track. But I don't hear it being applied to the track. I have, of course, toggled the Bypass button but it doesn't make any difference. I am monitoring it through my Mbox 2.

Any help or suggestions would be appreciated.

Thanks
