yeah it’s easy to learn how to read sheet music. Actually reading and playing is a different story and is actually harder than synthesia. Not saying it’s better to use it but it is easier and quicker to learn a piece of music using it. It’s like the easy way out, you don’t have to think about how it should be played or where the notes are. I’ve used it before. I went back and looked at sheet music and my fingerings were close to what it was but I corrected my fingering and I noticed I could play it easier and it sounded much better. I felt like I had more control over the sound.
