In security craft there is a sentry that listens to note blocks for a specific tune which then activates it, i thought it would be cool if the tune could be set with an instrument and maybe the tune only works when played on that instrument

Unfortunately it doesn't look like this is something that will be very easy to accomplish with how the mods currently work so I'm closing this for now. But I will keep a note of it and if anything changes in the future I will look into this more!

Hello! I can take a look into this, but there is a good chance that it won't be easily compatible unfortunately. MIMI exists entirely outside of the sound system that Minecraft itself uses so it's really hard to make MIMI interact with other mods that interact with the default sound system. I'll see if there's an easy work-around though!
