Thank you Daniel,
I did find the ‘split secondary beam’ option and that worked great for that measure. In this movement, this will continue to be a thorny problem as the balance between 3/4 and 9/8 parts is pretty equal. But I can grin and bear it .
I did actually find something that you may be interested in! Not a huge problem per se, but some strange behavior from Dorico (see attachment). In order to have engraving that matches the original score, I turned off a lot of the tuplet appearances (beams, numbers, etc). If I select a measure that is tuplet grouped (9/8), but with hidden tuplet beams/numbers/etc., Dorico will not paste properly, pasting the selection as if the notes were valued in 3/4. Pretty interesting! In other words, referring to the attachment, measure 1 is my unchanged input data, measure 2 is the same music but with tuplet appearances hidden/removed to look like the real score, and measure 3 is measure 2 copied and pasted. I did figure out a fix by just selecting the pasted music and appling a new tuplet to it. I thought it was interesting though that by removing the tuplet appearances, it seems to actually change the copyable information that Dorico is detecting.
I’ve spent hours working this out, and I think I’ve got hacks to make it look correct at this point, but I’ll just articulate my desire in a perfect world. It would be great if, when using interchangeable time signatures, one could apply each time signature to particular parts primarily for the purpose of NOTE GROUPING. This is a common practice notation in scores where simple duple and simple tuple meters are combined, but where parts don’t switch frequently (say, a tuple accompaniment under a duple melody). Right now this seems impossible further because I appear to need metric modulations (e.g. q = q.) to swap between meters. Lord knows what will happen if I try to enter that for individual parts .
For now I’ll just enter everything into 3/4, and remove the unwanted tuplet notations. It’s extra time but it’ll get things done properly.
This is too long, so I’ll end by reiterating my profound gratitude to you and the team for building this incredible product, and for being so active in responding to our queries. I plan on remaining active on here, but I do hope that isn’t interpreted as my being an overly demanding consumer. I am so enjoying plumbing the depths and figuring out how it thinks. This is an extraordinary product (the font looks gorgeous btw), and it is worth multiples of the purchase price to me. Thank you!
