[pluggo] Problems with midiformat & midiparse

Hullo,

I have been having some problems using midiparse and midiformat.  Currently I am trying to build a somewhat sizeable patch and my host, Live 6, just will not recognize it with these objects in.  It has found it when the patch was smaller, and does with other patches.  In the developer guide it says these objects are not supported (though I see no logical reason why) yet they are used in the tutorial section?!  Are there other objects I should use instead, or are there any good user made ones out there already?  

Thanks.
