Square Lead sound in MuseScore 4 has annoying low-frequency noise which was not present in MuseScore 3.
I've opened "MS Basic.sf3" from MS4 and "Musescore General.sf3" from MS3 in the Polyphone SoundFont editor and compare "square1" "square2" etc. samples side-by-side, and samples in the new bank are way noiser, you can clearly see it right in the waveform.
Comments
The same happens with other samples like "Clarinet G#4", "Clarinet G#5", "Soprano G#6", "Clean F67", "reed organ c6", "reed organ c7", "reed organ c8" etc.
It looks like many samples in the "MS Basic.SF3" soundbank were edited to alter sound level and/or frequency equalisatiion, and these edits amplified existing noise patterns in these samples.
