mode of expression has introduced a new ‘visual music creator’ for the Apple iPad, Noteplex:

Noteplex is an experiment to put music in a visual representation that’s different from standard notation or a piano roll.  Noteplex displays music like a hexagonal network of nodes and pulses, and it’s powered by a real-time 44.1khz sampler/synth.

The user creates a kind of musical chain reaction.

Noteplex is available now in the App Store for $1.99.
