Yes, but I would not have correct crotchets - in this type of void
notation crotchets are written out as quavers, with connected stems
and all, but with a white notehead.
I think I can:
1) write out everything in 3/2 and then alter manually every note <=
than a quarter to transform it in an eight
2) Halve all the values of the original, writing it in 3/4, then
blanking out all the noteheads (with duration-log). In this case all
the quarters are displayed corretly - they effectively become eights
with white noteheads - but (obviously) all the whole notes in the
original now are written as minims. I then manually turn off their
stem to make them wholes again. This is because I am faking 3/2 using
3/4 (for the abovementioned eigths).
I can do this all manually, but it is quite tedious and long, and in
clutters my code (since I have to torn off stems almost every 2 notes)
- a way of turning off stems for all minims would be much more simple.
Thanks,
Rodolfo
