Good and very cool sound visualization – NodeBeat - Playful Music Review

iPad Air 2, iOS 9.1 This app is very cool and works well, even with Apple TV Mirroring. BUT exporting of music created not really possible in free version, but gives the impression that it is with "Audio copy" function under recordings button. It tries to connect to a "Audio Copy server" but cannot do it. The format is not clear either, so not sure if you can use it with out app once copied, after server connection is possible.
