I wonder if it would be possible to integrate with something like EasyNPC (https://modrinth.com/mod/easy-npc) to have a NPC Band play a song together. Similar to the blocks we have that allow multiple tracks and instruments to play together but through the skin of a NPC instead.

Alternatively maybe we could add a function that skins the instrument playing box into a npc haha. But it would be fun to have a group of npcs playing through a song playlist in the spawn area.

@majorcyto Good news! As of MIMI version 4.1.1 this is now working for handheld instruments! If you link a handheld instrument to a transmitter and put it in the offhand equipment slot of an EasyNPC it will now play! Should also work any other entity that has a mainhand slot or an offhand slot that you can put the instrument into.

Block Instruments will unfortunately be a much more complicated thing to figure out since the NPC/Mob would need to sit at the instrument, but you can fake it with EasyNPC by using a hidden Mechanical Maestro to play the instrument and then posing the NPC to "sit" at a placed instrument.
