During a routine mining expedition in the outer regions of the galaxy five mysterious boxes of unknown origin were found. Rumours among the workers spread quickly that there was a strange feeling being around these boxes, as if time flows in a different way, not just forward but sometimes also folding back on itself.

To use this feature, you need to have at least two IAA compatible applications installed on your iOS (iPhone, iPad etc.) device, first acts as a host and receives audio stream, and second acts as a node (or instrument) and publishes an output. Also, IAA node can transform audio or MIDI signal sent by host app, and return it in a modified form.
