Tenori-on style apps for Apple's iOS have arguably lessened the appeal of Yamaha's light-up, grid-based hardware over the past couple of years, so it's slightly ironic that a version of the iconic instrument has now been released for iPhone, iPad and iPod touch.
The design of TNR-i, as its known, is broadly similar to its physical forebear: you get a 16 x 16 grid of buttons, with the horizontal direction indicating time and the vertical representing pitch. Buttons can be pressed to trigger and sequence sounds (up to 16 at a time) and you create song patterns (up to 16) and switch between them in real-time.
Just like the Tenori-on, TNR-i can operate in various compositional modes, but it also has a few new tricks up its sleeve. You can create songs with up to four other people over a network, for example, and if you have a Tenori-on or Tenori-on Orange, this can be used with the TNR-i to enable network functionality on that, too.
What's more, because the presets are identical, performance files between hardware and software versions are fully compatible and exchangeable.
TNR-i costs £11.99 and is available now from the App Store. What isn't yet clear is whether or not the app supports MIDI Out, which would enable you to use it as a controller for your software and hardware synths.
It remains to be seen whether a direct port of the Tenori-on will work in software - the joy of the instrument lies as much in its build and look as it does its feature set - but if you're an iOS-owner who's always liked the idea of the hardware but never felt able to justify shelling out hundreds of pounds for it, the app's appeal is obvious.
