Playback glitches
When playing any score of any ensemble size, solo or full symphonic, at some point the playback will begin to slow waaaaaay down to what sounds like a byte by byte glitchy- 8 bit audio. I already reset to factory settings and it didn't change it. I am not using any soundfonts other than the original now because I thought that might have been the issue, but it changed nothing. I've seen people attach scores to these to show how exactly the issue can be reproduced, but it happens on every score.

Presumably your system is just bogged down - too many other processes running and using CPU / RAM. Rebooting may help. Or just closing other programs, letting MuseScore run longer so it gets prioritized higher by the OS, etc.

The computer has 12 gigs of ram and I rarely run more programs than musescore at the same time. I’ve already rebooted and let musescore sit for a long time.

This does not help at all. The problem came out of nowhere, about a week ago, and nothing I try has any effect whatsoever. HELP!

On Windows systems you can look at the task manager to see what's running and using memory and processor capability. I'm not sure about other systems. If you can, look at this and see if there is something using up resources while your score is playing back slowly.

did that, nothing over 30-40 MB was running. Musescore was the biggest thing at 460 something megabytes. The program still has issues. I am using two soundfonts, both provided my the Musescore website; the sonatina orchestra and the HQ orchestral soundfont collection. only the woodwinds are using the sonatina while the rest are on the HQ.

Were there issues with playback at the time you were looking? Did any of the other programs have a high CPU usage?

Yeah I pulled up the task manager last night because it was getting so bad. No other programs had high cpu usage :/ just musescore

do you have a midi device attached? What soundfonts are loaded? This includes sfz's under the zerberus tab.

It might help to know the I/O settings.
I am having a similar issue, but my issue is related to some MuseScore_General.sf3 patches - the only Soundfont loaded. I have 8 instruments in a work, one of them is an organ.
I have trouble with the organ when using the Drawbar Organ patch (my preference here) or the Detuned Organ patches. It is the same whether I use the normal or expressive patches.
If I isolate that instrument with those patches as solo (only that instrument plays) or as muted (only everything else plays), the playback is fine using any API but also rather pointless.
As soon as I combine that instrument with any others (even just one playing one note very occasionally), I get the glitches as described using the WDM-KS API. Using any other API with that instrument combined with any other instrument, the audio is clear but the rhythm is all over the place and the instruments are out of sync, even within themselves in polyphony. This is the same if I have many apps running or just MuseScore.
If I use the Rock Organ patch (NOT the one I'd prefer to use) or various woodwind substitute patches (definitely NOT preferred), I can play all instruments together just fine with an even tempo and crisp, synchronized polyphony. In this situation, I can run many other apps with no effect on MuseScore.
This issue is duplicated on 3 different machines.
So, the issue involves specific patches for me.
(I have no MIDI device and the MIDI Input button is toggled off. MuseScore 3.2.3.7635 rev. d2d863f. Windows 10 64-bit 1903. 16GB RAM. 4th, 5th, and 7th generation Intel i7.)

Problem in Musescore's Fluid synthesizer.
If any "vol.env.delay" parameter is used in the sound-font, the delay grows and spreads to other locations.
This bug was discussed before. But so far, no improvement has been made.

Same problem for me. I've been working on a score, and as soon as I added the drawbar organ, the playback was choppy in between notes. No other issues with MuseScore on my computer, nothing else is running.

No midi device attached. No sfz's. I have, like I mentioned, sonatina symphonic orchestra and HQ orchestral soundfont, and the normal Musescore 3 soundfont.
