great learning tool – SoundPrism Pro Review

This app has many applications (no pun), but the coolest thing for me is using it as a tool for learning the basics of music theory. I bought the pro version and most of the add-ons after trying the free version. It's also a lot of fun and I often get lost in it and lose track of time.
Review by FU-that's my name on SoundPrism Pro.
