The iOS version of the world-renowned TENORI-ON brings you a completely new musical interface. Even if you don't know much about music, you can create music intuitively as if you were arranging sounds in space. The music that you see on the 16 × 16 grid of buttons is the music that is performed.

On the 16 × 16 grid of buttons, basically, the horizontal direction is time, and the vertical direction is pitch.By laying sounds on these buttons, you can combine rhythms and melodies to produce music. A button will glow when its sound is produced. The movements of the glowing lights produce a visual performance.

TNR-i can produce 16 types of sounds at the same time (16 layers), and it can remember up to 16 song patterns produced using those sounds (16 blocks). By switching between song patterns in real time, you can produce a rich variety of musical expressions.
There are six different types of performance modes that you can select for each layer. You can make elaborate music by combining different modes. In score mode, the most fundamental of the modes, you can arrange sounds horizontally (temporally) and vertically (by pitch). In the exciting random mode, the sounds that you arrange are not just played in order—the melody and rhythm constantly change as twists are added. In draw mode, you can perform music by tracing your finger across the buttons as if drawing a picture. In bounce mode, the glowing lights are like bouncing balls that produce sound when they fall. In push mode, you can continuously change the sound as you perform. In solo mode, which is fun for solo performances, you can easily adjust the speed of repetition and the pitch.

First, please try the demo. You can experience the joy of performance just by switching layers.
- Loading the Demo: From the menu (touch the display), touch All Blocks, iD-Xtra_uncTK, and then Load.
- Switching layers: Press R5 and the area that the 16 × 16 buttons are in at the same time. (You can double-tap R5 to hold it and make it easier to switch layers.)

The appeal of TNR-i isn't just limited to its faithful duplication of the TENORI-ON concept and its design and interface, which were developed under the supervision of Toshio Iwai.
If you are connected to a network, you can participate in TNR-i sessions with distant friends and others. Up to four people can connect to each other over a network and enjoy performing together at the same time. First, tap Clear and the display at the same time to activate the Game Center feature. Then, invite your friends, or use the auto-match feature to automatically select a partner, and start your session.
For more details, see page 23 of the internal manual.
Manual: From the menu (touch the display), touch System Menu and then Manual.

If you update the TENORI-ON (TNR-w or TNR-o) to version 2.1 and use it with TNR-i, you can participate in sessions using the TENORI-ON (TNR-w or TNR-o).
For details, see the TENORI-ON webpage at

The preset sounds of TNR-i are the same as those of the TENORI-ON, and the performance files are also compatible. You can use iTunes to transfer performance files saved on your TENORI-ON SD card to TNR-i. Of course, the reverse is also possible.

Please enjoy the world of TENORI-ON.

*** First, anyone who is experiencing crashing and weird behavior from the update, try deleting it and reinstalling, then reboot your device before launching the app, then launch the app first thing once you've started up again. I hope this helps. :) ***

As for the app, I was excited to see some sharing options via a server in the latest update, like the Korg iMS-20 app has. But I was bummed out when I saw that I can only access it if I have a tw*tter account, whereas on the Korg app this is not necessary.

Also, is it just me, or is the settings section sort of a disaster? It pops up with like, 10 different vague headings, and it's really difficult to make sense of it all. Is the original hardware version's settings control this unintuitive?

Sounds are cool, unique sequencing tools are rad, and it has audio recording and copy/paste as well as WIST sync, so there's a lot if cool stuff going on here, and the app is really deep as far as the level of control offered.

I love what Yamaha has made for years, and it's great to see them working with iOS software, but while TNR looks very nice, it really just needs more work to be a little more immediate and usable like many of the other major manufacturer apps.

I hope you continue updating it guys!


Thanks for the fix Yamaha!

Yamaha has addressed the issues with the v1.4 update and all seems to be working well again! If I were only comparing it to the hardware Tenori-On, I would rate it 5 stars - It does just about everything the hardware version does... but it also doesn't do any of the things the hardware unit doesn't do, and there's some room for improvement. Musically, I find Tenori-Ons to be rather restrictive, but if you can learn to work within this framework, there's some good music to be made - music which you might not have composed otherwise.

Brilliant Instrument and Toy!

Ever since the Tenori-On came out, I've wanted one. The instrument is a piece of art that you use to create art. It's ingeniously designed, and especially for people who are visually and musically intuitive, its interface is really neat. Layers, blocks, voices, etc. can be changed using button shortcuts that combine the Left and Right buttons with rows, columns, and points on the grid. And until you figure out the shortcut buttons, there's a great menu system.

Especially since adding MIDI abilities, this is a powerful instrument for creating music. It's also very intuitive and fun. I hear it's beautiful on iPad.
Personally, I only have an iPhone, and I'm shocked at how well it works. Don't expect to get the right note the first time every time on the small screen. But it does work. And I love having such a fun and powerful music creation program in my pocket.

Six stars out of five. Thank you, Yamaha, for making the Tenori-On experience available to so many folks with this app.

(BTW, there have been some complaints about glitches and stability in the past. As of Feb 2013, it seems solid.)
