Musescore 3.0 Sound Crackling and Popping

• Jan 9, 2019 - 22:24

When I play back a piece on a concert band template, the sound cracks a little and it does it on all instrument parts. I believe it does this with a large amount of instruments only because on chamber templates or solo instruments, it does not appear to happen. Musescore 2 plays it just fine, but it does not seem to be working as well with Musescore 3.0. It might just happen when most of the instruments are playing but when I solo them, they still have that crackling sound.

I think you suffer the "Mac Stuttering problem" which came in with 2.2 and is not reproducible by the staff. I have {OS: macOS 10.14, Arch.: x86_64, MuseScore version (64-bit):, revision: c1a5e4c} and my processor is faster than yours (2.3/i7), but 6 years old, and have been plagued by stuttering since before either Mojave or MS3 (but it came in with 2.2 if I recall). I have reason to suspect that processor speed is a key factor in this problem. It seems unique to Mac.

yeah, I have that same problem, a real shame seeing as I moved all my pieces over to MS 3. Hoping this can be fixed in an update preferably very soon.

I too experience crackling on a recent version of MuseScore 3.1 on my MacBook Air (13-inch, Early 2015, details below).

The workaround for me has been to quit and restart MuseScore. I find that the problem develops if I have done almost anything else on my mac since starting MuseScore (especially anything having to do with audio, it seems). So I have developed the habit of quitting and restarting MS whenever I start work on a score. It doesn't seem to develop while I am working very often, but occasionally that happens.

So, that might be a workaround for others. But if anyone has a better workaround or a fix, that would be appreciated.

I tried it just now - fresh reboot, no other apps open - and it seemed to have helped significantly. There are still very slight pops here and there in the louder sections, particularly when a lot of instruments are playing - I'm transcribing Mendelssohn's Hebride's Overture - but the really big nasty crackles seemed to have gone away.

Excellent suggestion!

Perhaps a memory-leak problem?

I've had this problem intermittently since 3.0, including after acquiring a brand-new Mac with 16GB RAM. It has gotten somewhat better over time, but is not gone. It seems endemic; it is not reproducible enough that maintainers can do anything about it.

There used to be a terrific score of that very famous overture, but, like the people who post them, scores come and go, and it seems gone (or maybe search just didn't find it after 2 or 3 tries). Many people old enough to remember classic Warner Brothers animations will always associate it with a very zen Mynah bird ...
