@Prowl8413 There aren't future plans outside of it just being diverse instruments. They're more of a social feature than a gameplay feature.
One thing it can do with the normal goat horn is that you can hear the sound from very far away, so it can be used to locate your friends on a server
@navyxus @Prowl8413 I'm not sure that's actually the same with sound effects though, but do feel free to give it a shot in multiplayer and see if it works!
