Developer Agoston Nagy has introduced SoundBow – a drawing-based music instrument with a simple visual interface.
SoundBow is designed to let you create music by drawing curves over the screen.Each time your ever-looping gesture hits a string, a sound is produced.Your gestures will be remembered and played back continuously.
Apart from drawing, you can experiment by moving the strings around freely to rescale your instrument. You can also record any sound through the microphone and create melodies, soundscapes with your samples.
Here’s a video demo:
SoundBow is made with free and open source tools. The interface is built with OpenFrameworks, for accurate polyphonic sound sample playback, the sound engine is made with SodaLib, a free Data Sonification Library built on top of libPd (Pure Data).
