Many thanks for the comments, and for the advice about conventional usage.
I am only creating printable notation (playback not required), so your second suggestion would work. The other possible solution could of course be simply to change the clef! I'll see which looks clearest.
Hi, I'm (still) a happy NWC user, and have just found this user object, which is just what I need. I hope it's still being maintained.
I have a 2-stave composition, and want to make the top stave an octave lower with the label text ABOVE the stave. But there seems to be no way to flip the ending mark downwards, so the rendering is wrong.
Is there a workaround? Or can a future release include an option to allow the orientation to be toggled?
