Hello,
Thanks for your answer. I use Musescore, BIAB on my Mac and Symphony Pro5 with my IPAD.
With BIAB, not a real problem because the notes are imported as Melody and you can kill easily the whole melody. With Musescore, you have to select the notes and delete them. Not the best but it works. With Symphony Pro, when I delete the notes I delete also the chord symbols at the same time! And that’s the problem! I can of course export to BIAB, clean and import in Symphony Pro but it makes things complicated when they could be simple, if I can say.
