From Przemyslaw Wrzesinski:
iContinuum is a program converting a signal from touch screen to sound. The sound is generated from the coordinates of your touch. It's something like a keyboard, but the most fun is that it's countinuos, so there's no problem with playing a tone "beetwen tones".
For playing I recommend turning the device 90 degrees left. The more to the right you touch the screen, the higher the sound is. The more to the top you touch, the more effect is added to the sound.
The iContinuum is capable of processing up to 5 different touches, but it can slow a bit when playing them, so I recommend no more than 3.
It's hard to show music on a screenshot, so if you want to know hot iContinuum is working before you download it please visit my site. Have a good fun ;)
