Expected behavior: Different ways of getting to the same goal sound the same on playback
Actual: Chord on one staff (using 2 voices) sounds different then chord through different staffs
OS: macOS 10.16, Arch.: x86_64, MuseScore version (64-bit): 3.6.2.548020600, revision: 3224f34
I put the exact same notes together (two voices, same note) on the bass and it sounds one way. Then, I put two notes (same pitch, one is on the baritone and the other is one bass) and they sound different. The other bug is that the sound keeps changing for the 2nd one.

This is an inherent issue with synthesis - having the same exact sound sampled played twice at the same time will result in all sorts of crazy acoustic artefacts, just the laws of physics doing their thing. It doesn't depend on one staff or two but on timing - even an extra millisecond difference in the start times changes how the waveforms interfere with each other. Solution is to mute one of the two notes if you encounter this.
Someday it would be nice if MuseScore detected this and muted one note for your automatically (or otherwise modified one to make its waveform different enough to not cause these issues), so I'm leaving this open as a suggestion for such a feature.
