Player distortion - possible bug in Mac?

• Aug 14, 2019 - 08:31

I’m using the latest version of Musescore (3.2.3.22971) with Mac OS Mojave 10.14.6 on my new Mac Book Air.

When I write musical notes, the sound is distorted with a kind of delay. The same thing happens when I play back what I've written especially with lots of instruments.

I’ve tried to install a new sound library but the problem persists.

I’d really appreciate some help in this matter.

Generally, this indicates you system is low on resources. Rebooting may help, also just starting and restarting playback a few times to make sure the necessary information is in memory so your OS doesn't need to "swap" it in from disk. Or, install more memory.

Did you delete it from the synthesizer so that only MuseScore_General.sf3 shows?
Is the synthesizer loudness meter red-lining during playback?

Do you have any MIDI hardware attached?
Any bluetooth (e.g., headphones)?

Try changing I/O parameters in Edit -> Preferences -> then click on I/O tab
