Bouncing balls turn into music!

Arpie is a novel musical app that allows anyone to enjoy music. Put balls as many as you like, them watch them playing a beautiful melody. Higher balls hit the keys with long pauses, and lower ones hit them fast and repeatedly. By combining them, you can easily create a wide variety of musical sequences.

Easy to use and create music

This is easy to use and create sound patterns. It really is quite a clever approach to music making. It would be better with a save pattern function.

Very relaxing sound samples - good bit rate. Would pay for a save function, and also, a pause function to edit out unwanted notes. Good stuff! Thank you :D
