The iOS version of the world-renowned TENORI-ON brings you a completely new musical interface.

Even if you do not have any musical knowledge, you can create music intuitively by "placing" sounds on the 16 x 16 button grid that are performed musically and visually.
On the 16 x 16 grid, time is represented horizontally, while the pitch is represented vertically.
Both rythm and melody are combined on the grid to create music.
When the sound is played, the buttons flash which also provides a stimulating visual performance.

Up to 16 tones can be played simultaneously (16 layers), and it can store up to 16 song patterns in memory (16 blocks), which can be activated during a performance in real time to produce a rich variety of musical expressions.

There are six different performance modes for each layer:
- Basic score mode: time is on the horizontal axis and pitch is on the vertical axis
- Random mode: Sounds are played in the order that they were entered, and rotating the device produces a cascade of changing melodies and rythms for your enjoyment
- Draw mode: Sounds are played in response to dragging your finger on the grid, like drawing a picture
- Bounce mode: Sounds are produced when the lights fall, just like a bouncing ball
- Push mode: Continuously change the tones as you perform
- Solo mode: Easily change the speed and pitch to play as a soloist

First, have fun with the demo version. Just changing between blocks gives you the feeling of a real performance.
Load the demo:
(Touch the display) Top Memo -> File Menu -> All Blocks -> iD -> Xtra_uncTK -> Load

TNR-i's attraction is not just its faithful reproduction of the TENORI-ON feel or Toshio Iwai's design and interface.
TNR-i can connect friends and other TNR-i users via a network connection for session performance.
Up to four people can perform music together over the network.
For details, see page 23 on the internal manual.

Bug in random modes

After a short period of use, the random modes sometimes fail to 'run', and wont register and hold any buttons. Sound is only made when releasing buttons. This can happen in any or all random modes 8 to 11.

It functions correctly after a reset in the system menu, but eventually goes wrong again.

Same behaviour on iPad Air & iPhone 6s, iOS 10.3.1

Otherwise, nice!

Not bad but!

Ok, I own a Tenpri-On so when I saw a software version I just had to grab a copy. The problem is that it is too much like the original version requiring multiple key presses to perform the most simple of tasks like changing layers or blocks. I feel like Yamaha have missed the point here and should have made better use of the screen space and at least provide decent song construction features. What is the point of having small buttons labeled L1-L5 and R1-R5 when they could have had well labeled buttons (layer, block, loop speed etc.). Just like the real thing you are forced to record songs in real-rime in a single take which is impossible!

For anyone looking for a good Tenori-On like program which takes this concept to a new level should check out Aurora which I feed is a much better program. The Tenori-On is a fantastic and unique piece of hardware but I don't feel Yamaha have done it justice with this software which could have been so much better.

If Ever an App...

...Required Ableton Link, this is that app (along with the other TNR app). Being able to sync this with other "Linked" apps would elevate it from useless to useful in one fell swoop.
