Request to add more Aux channels in the MuseScore mixer

Your idea

Hello,
I’d like to suggest an improvement for the MuseScore mixer. At the moment, it’s only possible to use two Aux channels, but in many music production scenarios it would be extremely useful to have more Aux channels (for example, 4 or 6) to handle reverb, delay, chorus, and other effects more flexibly.

This feature would make MuseScore much more versatile, especially for users working on complex mixes or orchestral scores that require multiple effect sends for different sections.

Would it be possible to consider adding this feature in a future version?
Thank you for your attention and for the amazing work you’re doing with MuseScore.

The issue requests increasing the MuseScore mixer from two Aux channels to four or six for separate effects such as reverb, delay, and chorus. No files, tests, or entry points are identified; first locate the mixer and audio-routing implementation, then define the supported channel count and verify that the additional Aux channels work in relevant mixing scenarios.
