I´d suggest to use the ~ only when there are several pitch changes on one syllable. When you just want to do divide a word into 2 syllables, there’s no need to use the ~.
Again a great work! The only thing wich is not so god in your txt"s is how you set the "~". Sometimes you forget to set them and in some txt you put to much of them... But it’s easy to fix, so thank you again for your work
