SoundZen is a new concept for music. It allows you to generate constantly evolving and changing music with no effort at all.

SoundZen uses a form of cellular logic to determine how your song evolves over time. It follows 2 simple principles:

1. When an arrow touches the edge of the grid, play a note.
2. If arrows collide they must turn 90 degrees for each arrow they collide with

You set up the app by touching any of the positions on the grid, touch it again to change direction and press play. Using the principles above, SoundZen will take you on a zen-like journey based on the input you gave. Sit back, relax and watch as your song changes right in front of you.

You can also save/load your songs and purchase new sounds from the store. After buying a new instrument you can change it by pressing the arrows above the instrument image.

Check out this YouTube video to see the app in action!

Good music app

Good app, but with the newest update, I can't use different sounds, like guitar, etc. It is stuck on default.

It's okay

All of the instruments beside a basic piano are lock with real money, but the actual way that you make the music is good.
