The attached cut-down project has one percussion player with two instruments. Near the beginning of the flow, the wood block has a kind of cadenza during two regular bars in the snare. This is notated with a local X time sig in the wood block and added barlines. (I’ve deleted a bunch of notes, because they’re not relevant here.)
Later on, there’s a instrument change to snare drum. In both the percussion part and full score, in Page view, in the measure where the snare enters on beat 2 of a 2/4 bar, the measure has a whole rest instead of the expected quarter rest. Everything looks correct in galley view, and everything looks correct if I disable instrument changes in Layout Options.
In the open meter section, if I delete the added barline, so that there are the same number of bars in the 2/4 and X sections, then the snare entry displays correctly.
Is there something I’m doing incorrectly here, or do I just need to fudge that rest?
Edit: The bar numbers are messed up in this file because I deleted so many things from the original project – but in the original project, they’re all correct.
I think it is something to do with the mix of independent time signatures. If you get the 2/4 back to a single time sig (including the double barline), it renders correctly. (but this might not be the whole story).
Yes, seems to be something in the independent time sigs and the different number of bars. The actual project has eight open time sig bars in the wood block for each of the metered bars in the rest of the orchestra, so I think there’s not a good way to change the notation.
@MarcLarcher 's comment about incorrect rests at instrument changes in percussion staves is interesting, but I don’t think that’s the whole story here either, since all the other instrument changes are fine.
In any case, does this seem like a bug? (Legitimate use of notation tools leading to incorrect notation.) Or is there some other way I could have achieved the same notation without the problem at the instrument change?
This is not so much a bug as a limitation in the way instrument changes work. Normally instrument changes occur at barlines, but in this instance (I guess because of the local time signatures), the instrument change is occurring at the position of the entry in the snare drum.
Dorico therefore ends up displaying the bar rest from the wood block (which is technically “at the start” of bar 0j), and then the snare note halfway through the bar.
What you need to do is create an explicit quarter rest at the start of bar 0j in the wood block, like this:
