I think we should welcome these questions here, as long as they are related to music. Even if you're not actively performing these tasks, it's good to know what the engineer is doing when you're in the studio.

Also, the status for sound design is unclear to me. Before when questions were suggested for migration there, it seemed their scope was not clear. Different communitites have been merged there, and there were difficulties coming to an agreement.

We should have very good reasons for disallowing certain types of question. If there already is a stack exchange where the questions are welcomed, that could be one. But I don't think that's the case in this example.
