MS 2.2 AppImage on Linux Mint 64bit: 2.0.x score gives synthesizer output artifact with new soundfont
I've been eager to try out the new MuseScore_General soundfont with 2.2, so I downloaded the Appimage and started playing with it. The new clarinet sound is a lot better, and the viola no longer has the pitch bend in certain notes (although the vibrato almost fooled me). I also tried a full orchestral score created with 2.1 and it seemed to play OK. But when I tried a score created with 2.0.3 , I noticed an effect that I can only compare to the effect of an endless cumulative reverb - a background sound like an infinitely sustained chord that gradually builds up.
Was this expected? What would be the procedure for updating 2.0.x scores to play correctly in 2.2 with the new soundfont?
