mode of expression has recently released Noteplex, an iPad app that lets you make music through chain reactions.


noteplex presents composers with a hexagonal board of cells on which can be placed nodes. Each node has a sound associated with it, such as “Electric Bass” or “Snare Drum”. [You can use your own samples, too!]

A noteplex song begins when the first node fires a pulse. These pulses hit other nodes, which play their sounds and fire more pulses. Those new pulses hit other nodes, and so on. You’re hearing a noteplex song!

Share your best work online and explore what other noteplexers are creating. Favorite your faves and see what’s getting attention.

Everything from drum loops to “Happy Birthday” to extended compositions can be created with noteplex. This radically different paradigm for composition will push you to new and unexpected places creatively.

Noteplex for iPad (iOS 4.2 or higher) is available to purchase for $2 USD. iPhone/iPod version coming soon.
