Oh that is concerning. I’ll try it, but hearing that I’ll probably stay with version 3.7, or switch to Tenacity if it adds realtime effects.
Muscore 3 is only archaic according to the lead developer of Musescore 4, and he is rather biased. In my experience it completely broke my workflow and supposedly added a new playback engine that doesn’t seem to exist.
The numbers aren’t random. They are sequential. The early digits are assigned geographically, but the rest are in sequence. If you know a valid social security number, adding or subtracting 1 will be another valid social security number, most likely someone born in the same hospital on the same day.
They did change it somewhat recently, but they don’t re-assign the numbers when making that change, so most of the numbers are completely insecure.
