Hey Guys,

     I came across some intriguing free plugins in VST format.

     Does anybody use VST via "wrapper"?  Curious if it's a pretty easy, seamless thing?  Are 
they heavy on CPU because of the wrapper?

     Here's the ones I found:   http://www.madtracker.org/plugins.php?author=Elogoxa

     Take care all!!
