In the example given the gliss (continuous) works fine but the second note (where gliss finishes) stops abruptly about half way through the bar.
I’m probably missing something very obvious, any ideas what it is? Thanks.Gliss shortens following note.dorico (921.1 KB)
Maybe a pic will be more immediately helpful than the example project link I posted. So, following the gliss, the C stops abruptly about half way through its length. I can’t see why that should be. (Remove the gliss and the note plays through its complete tied length; insert the gliss and it terminates early.) Does anyone have any ideas as to why this should happen?
The playback works correctly here, using NotePerformer. So I’d guess the problem lies with Vienna Synchron Player.
Thanks for trying it, much appreciated…I’ve continued to experiment to see what I could discover. It seems that by changing the time signature from 3/4 to 4/4 the playback works correctly. I can’t see why the time signature should have any effect on this? I’d have thought that seems to point more to Dorico than the Synchron Player?
You can experiment with any of the Dorico Playback templates - it works with them all.
For me it works in 2/4, 4/4 and 5/4. But not in 3/4.
I even tried adjusting the 3/4 instruction to [1+1+1]/4 or [3+0]/4 to see whether that had any impact, but the note still cuts out.
Have you tried not using Synchron?
Yes. You’re quite right. Using Halion there’s no issue.
Unfortunately Halion is not an option (in fact because here I’m using a Basset Horn I think VSL is probably the only option.)
Acoustic samples has a very good basset horn 
and there are probably others I’m not thinking about (really go and have a listen to those VWind instruments 
)
I just tried my playback template on your file and the note is perfectly rendered.
the problem here is that the VSL legato with many instruments, including obviously the one used here, cuts out after a time because the sample is not rebowed. And Dorico seems to automatically invoke a legato patch when implementing a gliss.
There are various ways round this but I would tend to choose the one of drawing the pitchbend manually – a value of around 5 seems to work for the semitone. This way Dorico does not invoke a legato patch. Just to be clear, the gliss can still be in the score, just the playback must be disabled in Properties.
Or spend some money – the Acoustic Samples basset horn suggested by Marc is €99
Or part of a bundle (VWinds Clarinets) with 8 instruments, at 199€ (and sometimes 149€). I’m not affiliated to them in any way, simply watch one of those Simon Passmore’s videos… It’s amazing!
@Brookland, interestingly using VSL Synchron-ized Special Edition plus (with Bass Clarinet, since it does not have Basset Horn), the Synchron Player switches to Sustain, after the gliss., so the note can be indefinitely long (I had to prolong manually the pitch bend though, but this is another question…):
the Synchron-ized SE does have the basset horn but I guess you only have volume 1? But indeed the bass clarinet holds a good bit longer than most of the instruments in that series. I guess they could simply record a longer sample! But both instruments (and others also) change to natural/sustain after the legato so the only difference seems to be the way the bass clarinet is recorded.
The VSL library has both a Legato (that holds as a “normal” breath length) and a Legato-sus (that holds indefinetly). Maybe a midi trigger for legato -sus could be programmed in the expression map (instead of using normal legato), or as Midi Trigger Region:
I tried changing the Expression Map to use C# – i.e the legato-sus patch for the basset horn but it still cuts out where it cuts out using gliss. in Dorico, even though with a simple slur without the gliss, the note is indeed sustained. There are a few strange goings on here in the VSL/Dorico combination – I still can’t work out why certain glisses work and others which seem virtually identical don’t. As has already been established, the gliss. tends to work fine with other libraries (one of the first I tested was NotePerformer which behaves as expected)
