Yamaha has released TNR-i, a fully-featured iOS simulation of Toshio Iwai's electronic musical instrument and Electroplankton successor Tenori-on.

Tenori-on operates via a 16x16 grid of LED switches, which can be triggered to play and loop a variety of sounds to a consistent beat. The effect is similar to the "Rec-Rec" minigame in the Iwai-designed Nintendo DS music sim Electroplankton, but offers much greater flexibility in terms of music creation. The iOS version additionally allows users to create music online with others via Apple's Game Center service.

The instrument itself is fascinating to watch, but doesn't come cheap; different models range in price from $700 to $1000. Yamaha's iOS adaptation, which is a universal build compatible with iPhone, iPod Touch, and iPad devices, is priced at $19.99.
