I will try to make this kind of rhythm machine where eternally bouncing balls will create the beat when hitting side of the screen(e.g. bottom). The speed of each ball could be adjusted individually and there could be also an adjustable overall tempo. The size of ball could determine the pitch.
I will send the parameter values through OSC to PureData  where I will do the sound synthesis. OF app will work as a visual playground for the hidden sound source.
This is the initial phase.
