The upcoming April release of Otona no Kagaku magazine, a popular science magazine in Japan, will also be including a special digital pocket keyboard that comes preloaded with basic samples of Hatsune Miku’s vocals.
The device comes with the amusing model number of “DSX-39”, and was a collaboration project between Yamaha and Crypton future media. It uses an eVocaloid “NSX-1” audio chip that contains the necessary audio samples, and is able to be played in real time. The device requires three AAA batteries, and has a USB port, but the device is not capable of exporting data to PC. Instead, a tweet by Crypton’s CEO Hiroyuki Itoh states that “you will be able to import lyrics and melody to the device via a web application”.
You can use the keyboard to make Miku sing in 3 different modes: A “do-re-mi” mode, an “a, i, u, e, o” (vowel) mode, or a preset mode of 5 other lyrics. It can’t do more than five sounds, so think of it as a sort of “super-lite” Miku editor. The device face has the keyboard itself, operated by a touch stylus, and 9 physical buttons for operation.
Buttons 1-5: sing a~o (vowels)
Button 6: vibrato
Button 7: shift
Button 8: volume up
Button 9: volume down
Button 7+1-5: choose preset lyrics
Button 7+6: Do-re-mi mode (sing the scale)
Button 7+8: octave up
Button 7+9: octave down
As it’s lacking in full-scale composition ability, and cannot export data, the device is not meant for professional use and is more of a toy for entertainment. But for those who get ideas for melodies on the go, and can’t be sitting in front of a PC all the time, this could be helpful for experimenting with those ideas.
