Love this app so much. Helps with practicing music, compose new materials, and choose from various types of instruments and keys. This is truly an awesome app!! But I only have one thing. I know they added the Chinese lute in the game and I was hoping an update would pop up for this app to add the new instrument. But other then that this is an extraordinary app to use!!

I’ll be using this a lot, thank you so much! It’s very easy to use and helpful too; it makes practicing so much easier 🥳

Should sound more like Sky itself

This is a great app for practicing music without other players but I feel the instruments should sound more like they do in game ao you know how what you’re would sound in game
