I just did a quick MusicXML export / import from Sib to Dorico 3.
I think it looks overall a lot better than when I’ve done this in the past, however it lost the tempo and all pizz / arco (stripped).
I’ve been told that stripping unknown stuff was fixed in 2.2, but clearly not.
Extra painful too, when you have to click on the pizz button for each note (can’t just select 5 staves and click on pizz). I have to say I really like and heavily use Sibelius multi-stave editing features.
Playback in Dorico is odd too, it insists on shortening the last note under a slur. Sigh. No matter what playback timing options I choose. So I can’t make it sound right, which makes it a non-starter for mock-ups for me. Oh well at least Dorico is moving rapidly and it will get there eventually!
