[MU4 Issue] No way to mute individual voices

[SamYeh]

Describe the bug
MU4 lacks the functionality to mute individual voices in a stave, which MU3 supports.

Expected behavior
User should be able to mute individual voices like in MU3, shown below:

Note: Am I missing something? I searched in GitHub, the musescore.org forum, and MU4 handbook and could not find anything related. Is this something that is planned for MU4 release / post-release?

This was a MIDI-based capability we had to drop for 4.0 but will re-introduce in later versions.

For context, MS3 was a MIDI-based app. MS4 does not use MIDI for its primary playback anymore. When using the Sound Font, this may seem like it's just the same thing with a few minor differences - but it was necessary for a variety of things we want to achieve in the future (as was something that allows Muse Sounds to sound so good too).

With this in mind, there were some things we just didn't have the time to replace quickly and felt it would be better to reintroduce them as part of a grander scheme instead.

Apologies about this. It's on our radar!
