I have a Sib4 score containing 40 staves, about 150 bars long. The score is in 4/2 time and to make it easier to read I want to halve the note lengths, rescoring in 4/4 time. "Easy", I thought, "Just run the 'Halve note lengths' plugin." Well I've tried, but the plugin consumes 100% of CPU activity and after about 20 minutes it had finished barely 10% of the conversion. I ran out of patience and hit [Quit] and the new score created by the plugin had reordered all the staves in the score. Not what I wanted at all. (The plugin did warn that it would do this, but I'd prefer if it didn't). Is there a less painful and quicker way to halve the note lengths? Doesn't have to be a Sibelius solution - I just need the job done. If I had more time I might try debugging the plugin (written in ManuScript) and see why it's being such a processor hog. (Keep meaning to learn ManuScript) Or do I just have to leave Sibelius running overnight and hope for the best?
