Musescore v3 nightmare lost settings, mixer, synth not saving to score
I have gone through periods of using Musescore for scoring and notating my scores. Very important. And have used Musescore for a long time via versions. Never had a problem until v3. I use windows but mainly today (as Microsoft has ceased Windows OS project from further development) linux, which suits my purposes as a professional with reliable and cutting edge audio tools. So I am referring a new installation on linux. I don't know if there is a difference in builds, but I don't it obviously, and otherwise prior versions of Musescore worked fine, saved fine and loaded old scores fine. Muscescore 3 is a mess and broken.
Like a word processor or office suite I would expect software, such as this to be stable, compatible without major bugs and errors in order to preserve important documents. I don't think it should be that hard: score, synth settings saved to score and mixer settings. But I have now found this to not be the case with Musecore.
I noticed the fatal bug of zero settings being preserved correctly recently after creating a simple 4 instrument score. In synth > I added the general soundfont + only 3 others (perfectly tested and fine). I saved to score multiple times. But after closing Musescore and revisiting, its all wrong, a jumbled mess out of order, including previous fonts including, loading from score does not restore either, etc. And even after manually getting the synth fonts (by clearing all but general! and then reloading and saving to score) to work, the mixer settings are wrong --- and I am well aware that synth font must retain original order, but still are flaky and do not retain. And after closing application all is lost. This again was definitely not the case with v2! I even installed an old version and checked this, and old scores load fine!
Worse, while on this new score labeled instrument settings and score correctly, I have also found the mixer all mixed up, no settings are daved properly, or even playing properly.
I imagine there are people who do not fully use Musescore with all its settings or who perhaps have older systems where they have not installed copies of the latest. But I have and 3 different systems in last year, I have checked each and same problems with settings not being retained.
The current version that I just tested this on was Musescore v3.3.4 Revision 7684abe
Now I have used Musescore for years without issue v2, for example. And now worse I have also found that opening previous scores, this same problem exists - all lost like aforementioned. I took notes and checked and everything is out of whack. And yes all library, fonts, etc are in fact maintained, existent, loadable, working, but not retainable after closing the session and Musescore application.
PS. I just attached a screenshot of the sidebar of recent post while composing this complaint and one can see related and basically same issues from others. Apparently this has been a longtime problem. And what's up with Telemetry? If Musescore is "totally free" - I don't find it very honorable and ethical to be collecting data from users or any excuse for it. Hope all this gets sorted out.
