Immersive Melodies

Immersive Melodies (Luke100000, immersive_melodies, v0.5.0) lets players compose and play custom MIDI melodies on in-game instruments — its own tagline is “play custom melodies on various instruments and annoy your friends!” config/immersive_melodies.json sets maxAudibleDistance: 48 blocks and stopGameMusicForPlayers: true (the ambient music track ducks out while someone’s actively playing nearby, so it doesn’t clash), while stopGameMusicForMobs: false leaves mob-triggered music alone. Mobs can also pick up and play dropped instruments themselves (forceMobsToPickUp: true), though several hostile mobs — wither skeletons, piglins, zombified piglins, zombies, pillagers, skeletons — have their instrument volume dialed down to 1% (mobInstrumentFactors) so they don’t turn combat encounters into a concert. A built-in keyboard-to-MIDI mapping (scancodeToMidi) lets players play live using number/letter keys rather than only uploading pre-made files.
