Comment 7 for bug 1825161

I am extremely sorry to bother u again, but I really tried to understand what am trying to achieve, but I simply can't. so, my doubts are:-
1. U said "Find the affected CO's in the code", so do I have to go through the whole list of controllers https://github.com/mixxxdj/mixxx/wiki/Mixxxcontrols or is it that I have to work only with the Microphone Controllers? https://github.com/mixxxdj/mixxx/wiki/Mixxxcontrols/49407737fa36c55d4570597803c7ed362a344309#microphonen

2. How Do I recognize the ones that are affected (or perhaps it is because I didn't understand the issue)

3.https://github.com/mixxxdj/mixxx/blob/9da873a777a147a3afadfb3a988ec42112359d1e/src/effects/effectrack.cpp#L431 here intellisense said `Adds a ConfigKey for 'alias' to the control for 'key'. Can be used for
supporting a legacy / deprecated control. The 'key' control must exist
for this to work.` Not sure what's confusing about it.

4.In the bug Description by ronso0 he asks about numbering the microphone's input like the aux inputs, moreover [Microphones],show_microphones, [Skin],show_inputs or, [Skin],show_mic_aux are to replace the controllers in the codebase, right? if so I can't really find the controllers which will be replaced by the above mentioned names(like what will show_mic_aux replace?).

Once again sorry for the trouble, I just wanted to clearly understand what is it I am working on.
