Glissando glitch at note ends in playback

Hi everyone,
I’m experiencing playback glitches at the ends of all notes that have been altered with gliassando. Particularly in vocal line playback (HALion Sonic, all the built-in Dorico presets). i.e. I have a gliss from Note 1 to Note 2. At the end of Note 2 (followed by a rest), I always hear the playback note snap back to the original pitch. I guess this is intentional, since if there was another note rather than a rest after Note 2, it would need to have its pitch bend reset. However… apart from adjusting all of the pitchbend data manually (there are a huge number of instances in this score), does anyone know any workaround or a way to finesse this automatically? I’ve already turned off all reverb, so I know it’s not just the tails… Anyone else experiencing this?

I need to give a playback mockup to the singers to aid learning, so I do need to eliminate these pitch snaps.

I’m not able to reproduce this at my first couple of attempts. Can you attach a minimal project that reproduces the issue, so I can take a look and see what might be going on? Just cut the project down to a single instrument and a bar or two of music, and attach it here.

Hi Daniel, sure, I just copied a few bars into a fresh project.
I can manually adjust the MIDI pitch bend for each note, but that is gonna be a huge job on a whole opera score.

I have noticed that as well. Also sometimes when adding a glissando the played initial note gets way longer then the second one. And therefore it snaps back to it and holds it. When shortening it manually the pitchbend disappear … when I’m back in my studio I will post an example

@Major81, by default Dorico plays glissandos “delayed”, i.e. it only starts moving towards the destination pitch in the second half of the duration of the first note. You can change this either by default via Playback Options, or on a per-glissando basis via Properties.

@Schweinhorn, thanks for your example. I’m not sure how we can best improve this. The pitch bend messages are in exactly the right spot to ensure that the pitch is reset before an abutting note, but the Olympus Choir Micro sounds seem to have a very pronounced release after the note off message, which persists even if you dial the Release parameter right down to zero in the HALion interface.

If another note starts immediately following the destination note, we’d need to keep the pitch bend reset exactly where it is now, otherwise the start of the next note would sound at the wrong pitch.

We’re loathe to add special cases for individual patches (quite apart from anything else, we can’t actually tell whether a specific patch is actually being used for a given voice, because we can’t “see inside” the VST instrument to know what patch is loaded – the user might have changed the patch).

So for the time being I’m afraid all I can really suggest is to use a different patch for your voice instruments.

Hi Daniel. Thanks for taking a look — yes I assumed this would be the issue. Thanks for suggesting a different patch; I’ll try that.

I know that. But I’m afraid it’s not what I mean. Anyway, I can’t reproduce the problem, so I think it’s not relevant anymore. Still another strange thing happened. As you see in the video, the drawn generated pitch bend glissando changes to chromatic steps, when I make any changes. I have to go to the expression map and make a change in the pitch-bend-range, and it’s like normal until I make another change in stave. But it only happens in the second violins. The firs violins use the same expression map but the problem isn’t there.
