Request direct way to change playback effect of articulations

  1. Select a note and add an ornament to it by double clicking in the "ornaments" palette.
  2. With the ornament selected, change the "time stretch" value in the inspector. For example, increase it from 0.1 (the default) to 0.2.
  3. Deselect the ornament then reselect it again. The value in the inspector has gone back to 0.1.

I can't find any way to change the value and make it stick.

MuseScore running on macOS.


Priority P2 - Medium

That time stretch value is meaningfull only for very few ornaments/articulations, like the fermatas, and apparently can only get set for those.

Guess we'd better not show that setting for those articulations where it isn't honored.

Even better would be to make it actually use the value. It would be nice to be able to set the speed of turns, trills, etc.

For tenuto a certain stretch is built in, and possibly different per instrument. same for staccatissmo, staccato, portato, marcato and sforzato. For fine tuning these use the piano roll editor

Tenuto doesn't have any time stretch (i.e. the tempo does not change). It does remove the gatetime, which means the note is held for its full duration rather than being cut off slightly before, but tenutos are often used to indicate that a note should be held for longer than its full duration (i.e. the tempo should slow down like for a fermata). This is not something that can be controlled via the piano roll editor.

Regression No Yes
Workaround No Yes

My sense is that that it was indeed never intended that stretch would apply for anything but fermatas, and this may have actually been part of the reason fermatas were pulled out of the Articulation class and made first class elements of their own - to avoid people accidentally setitng stretch on anything but a fermata. See for instance the discussion in #232056: Time Stretch with Multiple Voices, and the confusion users are having in support forum threads like

No doubt this change simplified some other things and probably fixed a number of fermata-related bugs along the way, but if it's common to rely on them to act as mini-fermatas (a usage I was unfamiliar with until recently), then it would be good to revisit this. Unfortunately, I fear it may not be trivial, which is why it's important to really good a handle on how common this usage and expectation is. I still kind of suspect at least some reports where people are asking about this are cases where people are confused and think this is going to just make an ordinary legato and not are not realizing this would actually convert the tenuto into a fermata.

For the record, adding invisible fermatas are the workaround for playback purposes.

I'm much more interested in ornaments like turns and trills. Being able to control the playback speed for those would be great. This would not affect how long the note lasts, just how it is played. This is similar to the (really useful!) feature that was added in 3.0 to change the playback speed of arpeggios.

@peastman, time stretch already has an accepted meaning of temporarily slowing down (or speeding up) the tempo for all instruments, so it is not appropriate to use it for other things like trill speed or legato/staccato of a single note or chord. There are other issues for those things, which you can find by searching. This issue is purely concerned with whether fermata-style time stretch should apply to elements other than fermatas.

I don't much care what the option is called. I'm just saying it would be a useful feature. Note, however, that the existing option for arpeggios is in fact called "stretch", so that word is already being used to mean two different things.

TIME STRETCH: You see? You got me in trouble! Now they're gonna get rid of me!
TRILL: I'm sorry! I didn't mean to do it!
TIME STRETCH: You little snitch, I'll get you for this!
TENUTO: You leave him alone, he's just a child!
TIME STRETCH: Shut up, you're next!
LONG FERMATA: Let me tell you somethin' boy. You want a piece of them you gotta go through me first. C'mon, big mouth! Come git you some!
TIME STRETCH: Uh, I don't want no trouble, country bumpkin....
HAIRPIN: What did you call me?

LONG FERMATA: Well if it ain't a cop when you need one. There's the one you want, officer.
TIME STRETCH: I didn't do nothin', see? I'm innocent!
BSG: All right you, both hands behind your back. Clancy...get the cuffs.
CLANCY: Um, we're inside a bunch of musical notes. Am I drunk?
BSG: Of course you're drunk. Now hurry up with those cuffs already! He's getting away!
REPEAT SIGN: I'll trip him up. He won't go far.
TIME STRETCH: Foiled again! I'm back to where I started....
TRILL: Works every time!

Regression Yes No

Why is this a regression? We've never supported this. If the "regression" is against 2.x, the behaviour then wasn't what we expect in this thread, which is about the time stretch for a single chord, not a whole segment.

This is indeed a regression compared to 2.x behaviour. Developers have only ever used the phrase "time stretch" to mean a temporary change in tempo (i.e. something that affects an entire segment). Users have seen the time stretch box (which currently does nothing) and wished that it does whatever they currently want it to do, but it would be a mistake to use the same label for something other than a tempo change. (Perhaps it should be relabelled "tempo stretch" everywhere, including for fermatas?)

It never did what most users probably assumed it should do, but it did something, and now does nothing. So technically a regression, although not a distinction that really matters. I would personally rather not see it go back to doing the wrong thing as it did in 2.x. I’d rather see it implemented in a way where it does what people expect - and be renamed in the process.

Potentially, yes, assuming MuseScore 4 provides a way to actually do what the user has wanted from the beginning. The Piano Roll Editor and @BSG's plugins are the way to go now - well, those or a custom instruments.xml I guess if you don't need control over individual notes. So as a "Suggestion" for an easier way to control note playback durations, I'd still leave this open until something is actually implemented.
