Portamento glissandos cause squeaking at end

Here's a sound recording of it in the context of a larger work (unfortunately not a Minimal Verifiable Complete Example). It occurs in intervals at least as close as a minor third down.

Currently, I'm not really in a position to provide a sample score for that issue. However, I imagine that it's relatively straightforward to create a quick-and-dirty mscz file containing an MVCE.

I'm not hearing anything amiss in the example I tried, but if you are able to provide an example, we can investigate further.

The way I "attached" my previous audio example was by putting a hyperlink to an MP3 I had already uploaded to a Discord server. You don't have to upload it to Discord specifically, but as long as there's public access to the file, you should be fine.

Yep, I hear it now. Maybe it was there in my original example, but it's definitely much more obvious in yours - low notes show it more than high.

I find the same. Additionally, playback of portamento is not smooth (like pitch bends) - as it would be on a violin/cello. It's audibly a series of small steps - when sliding between two notes at fast speed this would not be audible, but for a medium or slow portamento gliss it's not really usable. Having read that portamento had been improved in 3.6 I'd been very much looking forward to a solution to something that's been commented on over years!

I've got the exact same issue glad it's not just me

This also happens in Portamentos that span less than an octave. See attached Score.
(Also, even if you move the last note to be a D it still happens)

I can confirm the "squeaking". My notes were only a third apart. However, to me it sounds like the end note of the portamento is sounding twice because the "squeak" seems to make the same sound as the end note, though the duration is shorter.

I agree. The portamento is not the smoothest, especially on a bowed instrument. Also, I wish the portamento was a little faster (or you could make it faster). IMO, the glide between the notes should be almost instantaneous, similar to a grace note. Instead of "wheeeeeee", it should be "whe". There is a clunky workaround. Shorten the first note's duration and lengthen the end note so the measure timing is the same. And Yes, I did the ease-in/ease-out but it still isn't fast enough for me. This is probably personal taste.

This just happened to me on bass guitar part, if you push the 'ease in' to 100 and leave 'ease out' at 0, the squeak only occurred closest to the end. The squeak is still there, but you might just miss it if the tempo is fast enough and the length of the note is short enough.

Came up again in https://musescore.org/en/node/329009

Thanks! Had the same issue.

Just experienced the same glitch, both on Windows and on Linux. Hope that this gets fixed soon!

Already fixed for 4.0, feel free to help us test!

Hello, thank you for the update!
I just tried the MuseScore 4.0 alpha from this thread: https://musescore.org/en/node/334200

(I had no idea that a MuseScore 4.0 was even being worked on, this was a pleasant surprise!)
I downloaded the Linux AppImage and tried a portamento glissandi, but unfortunately, it seemed to still give that quick slide/pop sound at the very end of the glissandi. Are you referring to a future alpha version of 4.0 that will fix this, or did I maybe do something incorrectly?

Well, I'm using the currently nightly build which is a little more recent, but it should be working in the alpha. Must work for some scores but not others. Best to report this separately - in a new issue, preferably on GitHub as suggested in that announcement - and attach the specific score with the problem.

I can report that on the Windows 10 version of Musescore 4, there is still the squeaking with portamento. I am using the Alpha 2 version. Also, I don't know if this is related, but appogiaturas/grace notes appear to play in a different instrument (maybe piano). I included a score that has a lot of portamentos and appogiaturas/grace notes.
Oddly, there is also a piano sounding metronome sound that keeps playing even when the metronome is turned off. I think I figured it out, though. In the mixer panel, there is, oddly, a metronome sound that I can't get rid of or mute. If I turn the volume all the way down it doesn't play or if I switch the "sound" to a VST plugin it doesn't play, but If I keep it at MS Basic, it plays.
Lastly, when I downloaded and installed the program, it came up allowing me to download new sounds. I hit the "download" button, but nothing happened. I can't find in the menus where I can download sounds.
Thanks

Indeed, I hear the blip it in this score, although it's much more subtle than in 3.6.2. Could just be a matter of the re-articulation of the pitch. Anyhow, I'm leaving this open, not sure it will be seen by the folks working on such things, though. For best results, open a new issue on GitHub as mentioned.

I am not hearing any unusual metronome effects.

Btw, as mentioned in the announcement of the alpha, the new sound library is not available yet.

Thank you for responding. I agree the squeaking is more subtle. You have to really listen for it now. I will open a new issue on Github. You say, you don't hear an unusual metronome effect. Do you have a metronome "instrument" in your mixer? For some reason, there is a metronome "instrument" in my mixer that I cannot delete or mute (mute button is grayed out). If I turn the volume (gain) all the way down, it goes away, but that is a workaround, not a fix. Another workaround is to change the VST of the instrument.
Also, did you hear the unusual treatment of the appogiaturas/gracenotes? They sound weird, like the sound is from a different instrument (not violin).

Yes, it's normal for the mixer to show up in the mixer, it's how you control its volume. The mute button is grayed out because it is toggled from the playback toolbar instead. If you are saying it's turned out in your playback toolbar but you're still hearing it, sounds like a separate unrelated issue, but not one anyone else has reported, so we'd need more information to understand. In any case, again, not related to this, so best to ask about this on the forum if you continue to have trouble after making sure you've turned off the metronome in your playback toolbar.

Tried to upload a screenshot video of the "ghost" metronome playing, but oddly, this forum does not allow uploading videos. :~( My video capture program only has codecs for .mvw and .wav files.
Any suggestions to upload a video so you can see/hear what I am talking about?

Since metronomes aren’t related to this issue, best to open a new issue. As for the video, just upload to YouTube or the like then add a link here.

But first be sure to get a more recent build Al- the alpha 2 is months old now. The nightlies are best, but the beta will do. Also keep in mind 4.0 issues are to be reported on GitHub, not here. But first let’s make sure it’s not just a misunderstanding.

Thank you Marc. I did report the issue in Github and it allows an upload of a video. You can see/hear the video on Github in the issues section. I will get a more recent build (Alpha-2 is the most recent Alpha build, but there are the nightlies) and see if it still does it. By the way, what is the proper protocol for downloading a nightly. Should I overwrite my Alpha-2 build, or put the nightly in its own directory - trying to save HD space, if possible.
