I am inserting reaktor player instruments into my song , but while I can see they are playing I am getting no souond.  With the regular instruments everything works right.  It's only the Reaktor player instruments, Razor, rounds neither of which are  sounding.  But I can see they are working with a leveler of sound its just they aren't sounding.  Any ideas.

Can you please DETAIL how you have things set up, including whether or not you are using simple instrument tracks versus separate audio and midi tracks, as well as all routing assignments for all associated tracks.
 
Also, are the sounds you are trying to play, through the Reaktor Player, VALID for use with the Reaktor Player?  (If you aren't sure, do those particular sound presets play when running the Reaktor Player in stand-alone mode)?  If memory serves, there are certain sounds that the Reaktor Player can play, and it might be a sound that requires the actual full version of Reakor,
 
Thanks,
