Caelestis is a unique, sample based generative music app that creates sounds with bouncing balls. Three shapes on the screen are used as 'rooms' that contain a sound. Different coloured balls can be thrown around inside these rooms, generating notes when one collides with a side. Using different combinations of balls and sounds, all kinds of beautiful performances can be achieved.

More powerful than it seems

This little app seems and plays like a toy, but is quite extraordinary. I recommend the IAPs for full functionality. It's great for generative music and using its MIDI out feature is a lot of fun. The ability to import your own samples makes it extremely flexible. It's also so reliable that I frequently use it to test my system as I sometimes lose connection between my iPad and my computer. Well worth checking out.
