[Stk] New STK release (4.4.0)

[John Dey]

Gary,

Thanks for making your work available.  You probably have trained more  
audio programmers then you ever imagined.  I find it fascinating  
seeing how things work.

I do have a question:  The output of Md2Skini has the time output as  
zero.  Why don't I see the delta time?  I traced it back to RtMidi and  
it appears that CoreMidi is returning zero.  Is there an error in that  
code or am I missing something?

John
