More music items/mechanics
It would be nice to have more musical items like note blocks or even more instruments. I absolutely adore the music of core keeper and i would love to have more ways to interact with the environment. a nice addition would be a way to change the music in small areas like Terraria's music box, this could help with builds so that the music can always match the vibe. to expand on the note blocks, it can work with the wires, using circuits to help with timing. another change i think would be nice is to change the way music doors work. I have noticed that the notes on the door don't actually translate to actual notes, which stumped me the first time i tried opening one forcing me to just guess and find the notes. It would be nice to have that small change so that its slightly easier to figure out. Furthermore, I'm not sure if the notes are for lore reasons, but i think changing the melody to motifs from songs that play in that biome. An example would be having one of the doors in the dirt biome have the notes for Ancient Blue, or in Azeos' Wilderness having the notes for Light Traveling. This would give a small hint for each door and tie the music into gameplay.
