Where ist the "Play part only"-checkbox located in Musescore 4?

• Jan 3, 2023 - 20:49

Dear all, my Linux distribution upgraded MuseScore to version 4, but somehow the checkbox “Play part only” is gone from the mixer. Does anybody know where it is now? This was a particularly useful feature for practicing.
Thanks in advance for your answers.

Thanks, orMrSmith. Then my fears are true.
I had to uninstall MuseScore 4 and download the appimage of the previous version.

Unfortunately, the Solo-button is not helpful, as this way I still can't follow the score of a single instrument in a full orchestra score. It's not just about the playback, but about the notes. Without the possibility to follow the sheet of one part with the playback of the full score, I can't use the new version yet. I would be glad if this feature could be re-implemented in a future version.

Thanks, bobjp.
I know, and I often do that, too. But I have a small screen, and with longer parts, I can't see the whole sheet at a time. So, it was favorable when the cursor followed the notes. I mostly play from memory, but to learn the song, I need to see the notes for a couple of times. I think, I'll just stick with the old version.

Are there any plans to bring this feature back in version 4?

I'm glad that lureli raised the issue ... and that many users have confirmed their need for the Play part only checkbox.

The lack of Play Part Only is a serious MuseScore 4 regression. And it removed an easy, single-click method allowing us to read from a part while hearing the full score.

It’s terribly important to me to have the Play Panel reinstated in MS4. Not only for reading along, but to be able to hear and edit the Part and its layout while hearing the mix.

Additionally rather that it appearing only in the Mixer I'd like to see an instance of the Play Part Only checkbox in the Toolbar whenever I’m viewing a part, so I have the option of toggling the setting without the requirement of having the Mixer opened on screen. And it follows: When the user is NOT veiwing a Part then MuseScore would disable Play Part Only in the Toolbar. Assuredly Toolbar space is likely a concern but a small PPO button (with a Play Part Only tooltip) would suffice.

Unfortunately MU4's list of regression is longer than the list of new features. However this problem will be solved! The actual cause is that hidden parts are muted automatically and can currently not be unmuted. It's alsmost as if noone had thought about this basic need to proof read an individual part while still hearing the rest of the score...

Glad I found this thread, but ugh.

When you have a score with a dozen Instruments and you need to play a couple of them, and you want to know if you have edited those Parts properly, you need to follow only the Part on the screen, but you need to hear the whole piece so you know your context.

Is this a known regression? Has anyone reported it as a bug yet?

One more thing...

This seems more like feature disparity rather than a regression; ie, that it was removed on purpose, at least for now.

Anyone upgrading to MS 4 from a previous version should be presented with a listed of feature disparities so they can make an intelligent choice before proceeding. I now have a few scores I've heavily modified under MS 4, and I cannot play them properly due to this issue. And I can no longer open them in MS 3 to do the payback there. I tried doing an XML Export from MS 4, but MS 3 says the score is corrupt when I try to import it.

This is not a pleasant experience.

Yes I agree, luckily I had not made a lot of changes under Musescore 4 so have managed to get all my files back to Ms 3. It is not a finished program! So much is missing, it should have been released.
Sorry Musescore great program but if it works don't mess with it, one thing you need in this sort of program is functionally and lots of it, we musician are used to complexity, music scores can get very complex - once a feature is included it'll get used and you'll get this sort of response when you remove it. Staying with Ms3 for the foreseeable future!

Oh, are you speaking of closing the "eye" in MuseScore 4's Instrument panel which results in the odd behavior of MuseScore unsolicitedly muting the track as well?

Seems like this icon would be the more appropriate for that:

It's kinda like ordering a croissant and getting a coffee too. No doubt some people would like that, but may not if they have to pay.

I'm unclear on the design intent for linking sight and sound. But if it is deemed important, we could have three separate icons: eye, ear and a link toggle.

So, the function is indeed in MU4. It just isn't quite as simple.
In the mixer, mute the track you want to see but not hear.
In the Instruments tab, select the arrow next to the EYE of the first instrument you want to hear, but not see. A second eye shows beneath the first. Close that second eye. The part disappears from the score but you can still hear it. Do this for the other parts you want to hear but not see.
Not as simple, but the result is the same. I found this without much difficulty.
Maybe not better, but not a bug or regression. Just different. I suspect there is something about the playback engine that makes a single button difficult.

That's quite a lot of clicks to go between to the 2 states so not a practical solution for me unfortunately.
Sometimes I want to hear the part sometimes the band without the part and sometimes the whole thing.!
Sometime just a section. (I use it to check & rehearse the various parts).
I suppose I could have 2/3 iterations of the same file open and flip between the states that way?
But that is getting pretty cack-handed!
Sticking with Mu3 for the mo and looking at other software.

In MU4 parts do technically not exist. A part is a score with hidden instruments, which per se is good, I think.
The problem comes with musescores behavior when hiding instruments, that still hasn't been solved. Musescore mutes hidden instruemts and locks their mixer buttons. I think: It shouldn't do either of them.
Instead when you open a part it should be set to solo by default. The solo button would then work like the "play part only" check box. This would easily allow all three scenarios, you mentioned: solo the part (default), un-solo the part (hear everything), mute the part (hear everything, except the part).

Again, I suspect that it has to do with the playback engine. It is totally different. And probably not easily changed. Back when I had MU3 on my computer I never used this play part only thing. MU4 does it. Just not the same way. MU4 finally play pauses. That to me is far more important. But we all need different things. We need to use the software that works for us.

I read through the list of things not yet implemented in MU4. It seems to me that at least 90% of them have nothing to do with how MU4 sounds. People can't use MU4 because they are used to the way MU3 works. Look at this list of things that MU4 can't do. I do get it.
But there is one thing that MU3 can't do.
Sure, You can load 150 files into it and use it like a hymnal. There's save button. A camera button. Play part only. There's a stacking function. ASIO. No latency. And dozens of things that have to do with setting up and working with a score. All important to that end.
But there's one thing that MU3 can't do.
Sure, you don't need a very powerful computer to run it. There are many more shortcuts to do things quickly. The UI is familiar and easy to use.
All these and more are important to many people. I get it.
MU4 is different from MU3. Different. As in "Not the same Program". Different.
Nothing wrong with staying with MU3. Just because MU4 doesn't do the same things doesn't make it a Regression. It makes it different.
Can you imagine how the developers feel when they read some of the comments? They are told they don't know what they are doing. They released an bad, incomplete program. And worse.

Oh, what is that one thing that MU3 can't do? No matter how you manipulate it. No matter what settings you use. No matter what you add to it. It still can't do one thing. And, to use a phrase often used against MU4, it is a gamechanger for me (not that anyone cares). So much so that MU3 isn't on my computer. And I don't miss it.

The thing that MU3 can't do near as well as MU4 is make music. Yes, I know that notation software is meant to produce a printed score. MU4 can make music. Is it perfect? Of course not. But I much prefer things I've written in MU4. By a lot. I compose for playback. I need to know as close as possible, how my compositions might sound should someone be crazy enough to play them. Or I need the best playback for a stage production or video.

I guess most of that list will get added to MU4. Great. I hope they don't ruin it in the process.

Oooh pressed your button! Quite a tirade! - You're quite right horses for courses. I use MU 3 for making scores and printed parts for two bands. I don't need it to make music, everything I write gets played (well most of it.)
I use logic for 'making music' because I can record real instruments/vocals into it. (But it is pretty bad at manipulating printed scores!).
So MU3 it is for me until play part only appears in MU4.
It suffices.
