A broken piano or celesta chord sounds at the fourth beat of the first measure in the viola part. I have reproduced this in Musescore 3 Beta and Musescore 2.3.2. Operating system is Windows 10. It sounds at a low volume compared to the strings. soundcard is Asus Xonar DX.

I don't know. I've recorded both versions as wav files using Audacity, but I don't know how to upload them to you. The effect sounds louder on the 2.3.2 version than the 3.0 version. I've uploaded screenshots of the Synthesizer/Master Effects dialogs from both Musescore 2.3.2 and 3.0 Beta. On the Musescore 2.3.2 you will notice that the Output control is set to Wet, and several controls are altered. That was to help alleviate a whistling sound I heard in the slow strings (the soundfont that comes with Musescore) . I came up with that combination by trial and error. It worked somewhat, I did still hear a slight whistling like string harmonics. I don't think it has anything to do with it, however, because I never touched the 3.0 Beta synth controls at all. Thanks.

UPDATE: In both Musescore 3 Beta and Musescore 2.3.2, I opened the Synthesizer and set Effect A to "NoEffect". Effect B was already set to "NoEffect". Again, in Musescore 3 Beta I can hear the piano or celesta notes at the fourth beat of the first measure in the viola part. Again, the effect is louder in the Musescore 2.3.2 version but clearly audible in the Musescore 3 Beta version. I'm using an Asus Xonar DX card. Perhaps it's the card. I will look into it.

UPDATE #2: I ruled out the soundcard by plugging in my headphones into the motherboard audio jack. I was also able to rule out the soundfont by using a different orchestra soundfont that I had downloaded. I exported the musescore file to wav and heard the tones. But then I exported the musescore file to .mid and played it on Windows Media Player. The tones are gone. I think it is not an audio hallucination or anything like that. I think Musescore in being naughty somehow. Thanks.

I don't hear it as an arpeggio, but I do hear what sounds like a very high note (in version 3) with the note change in the viola on the fourth beat. I'm using the default sound font for the slow strings. I needed to mute the cello to hear it and it goes away when I mute the violin. I also didn't hear it when I changed the viola to two half notes.

The bottom line is you have to have both the violin and viola to hear it.

If the => means "oh, he meant 2.3.2", then you are wrong. As stated, the problem is first seen in 3.0 Beta. I then tried saw it in 2.3.2. It's happening in both versions. Also the strings whistle in 3.0 Beta just as they do in 2.3.2. For a while I accepted this in 2.3.2, but in 3.0 Beta? I don't think so.

Not to worry, no one is trying to dismiss you. The version field is just something we use to help us track how long a bug has existed. So if a bug existed in 2.3, we like to know that and have the info in the issue tracker database reflect that.

Btw, as a workaround, if the sound is bothersome to you, you can try a different soundfont - I do suspect the audio artifact is probably very specific to the samples involved. Unfortunately, preventing audio artifacts between all possible combinations of notes and all possible instruments is not realistic.
