Unfortunately I’m still in 3.5 so won’t be much help. But in general I found that to change the routing of a different staff of an instrument you need to create a new voice, either upstem or downstem. Otherwise Dorico will stubbornly persist on using the same VST for both staves.
Thanks for your reply, @Bollen. What you describe might work, but it’s not really feasible for my work. I’m really wondering if this is a bug or somehow intended behaviour. Maybe @dspreadbury could tell more?
It really shouldn’t be a problem, once you change the very first note on that staff it’ll persist for the rest of the score and it will have the same appearance. However, I will point out that I have now moved to version 4 and have encountered a bug that produces similar strange behaviour.
@Bollen Thanks, I have tried this again and again in version 4 and it just won’t work, even if I create a new voice. At least some acknowledgement from the Dorico team about this being a bug would be nice. It seems it is just not possible to change the routing to a different rack in the scenario described above.
Oh my dear Daniel, don’t take it as a criticism, I didn’t mean it like that at all. Since Dorico 1 playback and the Play window have been buggy, dodgy and unfinished. However, the notation department has been revolutionary! I accept that this is a result of priorities and if anything, I’m disappointed at how few DAW users have crossed over, NOT the development team.
I bought the Dorico 4 update back in March and still haven’t been able to use it. I did not request a refund and I have only inquired, not pressured, about when the bug might be fixed. I think that shows I’m patient and understanding.
