Calvin Flegal released “NoteCollide”, an AudioKit-powered iPhone and iPad app that allows you to generate music and sound based on physics.
Tap the screen to add the selected note shape. Use the music note button to change note shapes, use the Fx button to add Fx shapes.
Fx shapes need to hit the same type of note shape three times in a row to add the effect to that note shape.
Shake your device to cause a commotion.
Use the other controls to make the sounds more or less pleasant (tonality), or to increase physical chaos (weight).
