Re: Parallel music coming out in series

[David Bobroff]

I don't have the inventions available to look at but my memory says that 
the ornament should occur on beat 4 on the 'b8'.  You've put in too much 
skip time in the UpperOrnamentVoice.  It starts:

s2 s1

...which is equal to six beats.  Typo?  Change it to:

s2 s4

..or..

s2.


...and your problem should disappear, I think.
