SoundBow vs pocketOscilloscope

SoundBow is a drawing based music instrument with a clean and simple visual interface. You can create music by drawing curves over the screen with lines and gestural movements. Apart from drawing, you can rescale your instrument by moving graphical elements around. Record your own sounds through the microphone and start creating melodies, soundscapes with your own voice. If you wish, you can also export your composition as an audio file. "Touch-based mobile devices allowed interactive, gesture-based music production to hit the masses. So far, this type of musical creation hasn't exactly taken the world by storm. But SoundBow, a drawing-based musical instrument app, should shake things up a little bit with its clean, minimal visual interface and mesmerizing potential for complex, loop-based music production." - The Creators Project "Binaura bring their beautiful SoundBow app to iOS at last. It is a gorgeous instrument with huge possibilities for expression and creativity. I think that in many ways these are the kinds of apps that iOS was made for." - Palm Sounds SoundBow is made with free and open source tools. The interface is built with OpenFrameworks. The sound engine is made with SodaLib, a free Data Sonification Library built on top of libPd (Pure Data).
