Tenori-on is a new type of electronic musical instrument, developed by Toshio Iwai in collaboration with Yamaha. It's interface is a grid of 16 X 16 LED-illuminated button switches, in a frame that contains a few additional controls.

This device goes on sale in the U.K. soon. There will be a lauch event this Tuesday, September 4th.

  1. hello,

    I'm interested in your research as I'm developing analog devices for temperament. The first is an abacus where the beads control the cent value of each pitch, within a range. I'm looking forward to looking at your blog in depth.

  2. Research? I wouldn't have chosen that word myself, but it's nice to see it in print.

    I think there's plenty of room for experimentation, and wish you luck with your abacus approach.

    My own objective is to make another run at the app I wrote which turns a Macintosh keyboard into a musical keyboard, not because I think computer keyboards are particularly well adapted to the task, but because they're ubiquitous. The next version will probably require a 64-bit Mac running Leopard, because I want to invest my efforts where they'll do the most good in the long run, not necessarily to reach the widest audience right now.

  3. will you let me know when you have something to play with?

  4. Well, I already do, such as it is. If you go to...

    and click on the link labeled...

    "CLICK HERE for the last, working PPC-Mac version."

    it'll download a zip file that contains both a simple program for producing harmonic tones when you type on the keyboard, along with the source code, instructions in HTML format, and an admittedly paranoid license.

    The program was compiled on a G4 (PPC) iBook, running Mac OS X 10.3.x, and probably performs better on PPC Macs, although it will run on Intel Macs, courtesy of Rosetta.

    Be sure to read the instructions!

    You can actually pick out a tune using this program. Try setting the base tone to 11 Hz, and setting up the keyboard to offer harmonics 16 through 55, and then try playing something you've liked when you heard it played on a sax.
