Question

Is there an option to add sounds to the mod that are not included in the standard midi 1.0 General midi patches (which consists of 128 predefined instruments)?
I really liked this mod. But I don't like the standard "grand piano" sound and I would like, if possible, to try to replace it with something more impressive.

Hello! Apologies for the super late reply. Life got super crazy for awhile and I had pretty much no time for the mod. It sounds like you got this figured out, but if you're still having any issues please let me know!

Thanks @Merancapeman for helping to answer this! It is much appreciated.

Thank you @tofodroid for this amazing mod. It really is the best one out there for music and I'm glad someone with clear know-how has made it! It's my favorite.

That's it, right?

It shouldn't really matter where it is on your computer as long as the MIMI configuration has the correct file path. If you have a mod that lets you edit the configuration file in-game you can change it there, or simply go to the config folder in your Minecraft instance and look for the MIMI client configuration (mimi-client.toml) and search for the "soundfontPath" setting. Make sure your soundfont is a GM soundfont, and that it's not too big (mine is almost 900mb and works fine). Also make sure it looks like this in the config: "C:\\soundfonts\\exampleGMsoundfont.sf2"

Today, for the sake of experiment, I will try to put a sound font of 500 sounds, which in total weigh 30 GB. >:)

It's called a soundfont, which the author describes how to do. Download an appropriate GM soundfont and direct the mod to it in the config/in-game config editor.
