NodeBeat is a collaboration between Seth Sandler and Justin Windle. It was developed using openFrameworks, with PureData for audio synthesis. According to the NodeBeat website, "Octaves and Notes make up the two types of nodes. Octaves pulse and send messages to Notes within proximity. Each Octave is assigned a random octave and each Note, a random note; therefore, a Note will play in several octaves depending on the Octave it's connected to. Pause nodes to create your own beats or let them roam free to have them generate their own." Features include adjustable node physics, node add/remove, pitch shift, adjustable pulse rate and beat sync, adjustable echo, attack, decay, and release for creative sound sculpting, and for the iPad, audio waveform display and landscape/portrait views.
