SoundyThingie app for iPhone and iPad

SoundyThingie is an application that translates drawn lines into music. Additionally to just drawing lines it lets you modify them in a variety of ways, like moving them around or connecting them.
If you want to see it in action you can watch the video on the support website: http://www.soundythingie.net


The application starts with an almost entirely black screen, waiting to be drawn onto by you. Each line created results in a sound that is related to the way the line was drawn.

There are only a few principles that make up that sound. Most important are:
- The vertical position of a line determines its pitch. Lines at the top of the screen sound high, lines at the bottom sound low.
- Drawing speed determines volume. The faster you draw, the louder a line will be.

Besides that there are many buttons to press and knobs to turn which influence the sounds. You can later change a lines volume, attach other lines to it, choose from different waveforms.
You can also load and save your work, modify triggers and whatnot.

Theres a short interactive tutorial included with the application that explains most of the functionality and leaves some features to be discovered.
