When there is no sampled trill available then Dorico will naturally enough create a rendered one which is fine. But in a keyboard instrument using velocity as controller, even though a trill is created of individual notes which a human player could crescendo/dim through, Dorico seems to treat the trill internally as a single note and thus the dynamic cannot be changed during the trill. Now if the actual instrument can be programmed to be able to also respond to, say, CC1, then probably this would work but in most cases I think piano is velocity only.
So my question - is there any way, other than writing out the trill in full on a separate hidden staff, of actually getting Dorico to recognise a trill for dynamics purposes as actually separate notes?
Thanks @Nickie_Foenshauge , I tried again with a brand new test project and now it does seem to work OK, irrespective of VST used. I can only assume that in my existing project where it isn’t working that I’ve messed up the voice allocation so the hairpins are not been assigned to the correct voice somehow. That’s at least reassuring and I’ll take a closer look to see what I’ve done.
Glad to hear you got it sorted out. I will say, though, that in my test, one of the first hairpins I attached to a trilled note - and I can’t remember if it was with or without niente; I think it was both situations - there was no trill playback, just a single note. It may have been when I applied “Force generated trill” in the trill options, that fixed it. I am not sure about that, but after I applied and later removed this option there were never again any problems. So, something is clearly a little bit iffy.
with piano, a generated trill is always going to happen anyway as I know of no sampled piano which has sampled trills separately (and there would be no real point). As it happens, the first thing I checked when I came across the problem was indeed the trill options but no settings there made any difference.
As far as I can remember, it was when I enabled “Force generated trill” I got the first trill with a dimimuendo. Afterwards it made no difference, and as you correctly point out, it shouldn’t make a difference. But it did.
