Producing white (void) notation

In some French Baroque music, mainly in slow 3/2 time, a form of notation using open note heads was used, which is now known as “white” or “void” notation.

This snippet demonstrates such notation, by setting the property duration-log. Correct beaming is obtained by setting the music in 3/4 time and changing the displayed time signature using timeSignatureFraction.
