[MU4 Issue] UI response slow when using Muse Sounds #14430
Comments
I also have the same issue. Two different computers. Both with i5 CPU's and SSD's. One with 8 GB ram and the other with 16 GB Windows 10, version 22H2. |
@bobjp @MoritzBrueckner & @henkdegroot: Can you all check this build, which has a lot of performance improvements for Windows: https://github.com/musescore/MuseScore/suites/9417801459/artifacts/444885402 It would be massively helpful to get feedback on how much improved the situation is with this build. |
Hi, the lags are still happening for me unfortunately, which I didn't expect since in the very similar #14379 the same build seems to have mostly fixed the CPU spikes. If I had to make an uneducated guess I would assume that it's caused by waiting for the MuseSampler, I'm not sure if changes to that would be reflected in MuseScore builds since it's updated in MuseHub? I attached VS to the running Musescore process to maybe get more insight, I don't really have the time and disk space for the dependencies right now to build MuseScore myself. Unfortunately there is no CPU data available for the duration of the CPU spikes ( After selecting a different note but not non-sounding elements, the following is printed to the VS console (note the timestamps):
Perhaps related to this issue: #14383 (for me the lag also happens with non-sounding elements though). Thanks for your work, please let me know if I can help with something :) |

Not seeing any difference on my system when using this build. |
No improvement on my systems. Delay selecting anything in a score. Playback is now a bit garbled. Even with buffer set to 4096. Basic sounds work fine. |
Yeah, we've determined our performance improvements help a lot with playback but the UI problem is different. We have a pretty good idea why. We'll get back to you. Thanks so much for testing! |
This issue occurs in the 4.0.1 release for Linux under specific conditions:
System: Ubuntu 20.04, SSD, 16GB RAM, i5 3.5GHz |
@henkdegroot Please try it again. There were some performance optimizations previously, and the last one in #22595 https://github.com/musescore/MuseScore/actions/runs/8849899936 |
@DmitryArefiev it does seem to work a lot better. Also tested in 4.3.0. Excellent work. |
@henkdegroot Glad to hear. Thanks for testing! Kudos to @RomanPudashkin |
Describe the bug
See screen recordings. The same score being used.
First one with all instruments set to MS Basic, the response of selecting an item is instant.
Second one with all instruments set to Muse Sound, the response of selecting an item is very slow.
Difficult to see in the recording, but when the cursor stops moving I have clicked the object.
To Reproduce
Steps to reproduce the behavior:
Test with the attached scores
Expected behavior
Response of MuseScore should not be much different just because a different sound system is used.
