Waveform

The main purpose of making a local community is to aid discoverability of it on this instance, since that's the whole point of a music instance - sorting by local and getting music content. Adding to the sidebar is okay, but you'd need to do the same for every local (or relevant external) community to be fair and that's a ton of work (i assume) you don't need.

Picking and choosing different communities to x-post to is a lot of work for me, because I am really bad at categorizing stuff and most of my content coud easily be posted to several waveform communities at a time, because it's general production advice and free tools. Figuring out which tools are compatible with which DAW communities is not even something I can do to a decent degree and posting to every DAW or genre community about things applicable to all of them may become near impossible (and much more importantly it will spam the feed).

I'll consider fully migrating here when things settle down a bit, since there is a lot of talk (and action) about defederating certain instances or defederating by default if security measures aren't up to par, so having a big local userbase dampens the effect that has on discoverability really well (considering you have to go out of your way to find content from less populated instances.)

Thanks for responding and detailing my options here, I think I'm going to create an instance for music production here and cross-post for now if you give it a green light!
