Muted notes issue has worsened in 4.3

[NicolaRulli]

Issue type

General playback bug

Bug description

There has been for a long time a bug that led to playback randomly permanently failing to perform large swaths of notes until the program was restarted. It now consistently takes just a handful of minutes for that to happen, requiring a restart (and to go through the slow sample loading, and the resetting of the timeline's zoom). I'm picking regression due to the massively increased occurrence frequency

Steps to reproduce

1. work on a score for a while, having a decent number of measures (20?) and instruments (6?)
2. begin playback from any point You will hear that some notes are not played, and often even the entirety of the score past a certain point.
