Drum Plugin doubling in MP 9

[agfrag]

This is weird. I just downloaded the iZotope iDrum plugin trial and have been playing with it in MP 9. It has a drag to midi function so I dragged the midi pattern to the same track as the plugin, and now both the track I dragged in , and the plugin are playing on top of each other. I've searched the forums, the manual, and the internet, and not found anything,.

I used to use EzDrummer with Cubase, and it somehow knew not to play the plugin pattern once the midi for the drums was dragged to a track...but I can't seem to figure this out with PT. Obviously I'm a PT newbie. I think I've newbie'd just about every DAW software there is in the past 20 years!
