I purchased this new but never used it, so it's been sitting around. The box is damaged as it's a product from about 10 years ago. If you're interested, I look forward to your bid. Released April 3, 2014 ● Price: 4,980 yen (excluding tax) ■ What is Pocket Miku? Pocket Miku is a completely new music gadget that plays human singing voices. The heart of the device, which turns singing voices into instruments, is equipped with the eVocaloid-compatible sound source LSI "NSX-1" developed by Yamaha Corporation. The singing voice that flows through uses the voice data of the virtual singer "Hatsune Miku" developed by Crypton Future Media, Inc. With "Singing Keyboard Pocket Miku," you can make "Hatsune Miku" sing anytime, anywhere, with your own hands. ■ How to Play The playing method is simple: just touch the keyboard (keypad) printed with carbon material with a stylus (touch pen). In the basic settings, it is set to sing with the scale and voice of "Do Re Mi Fa So La Si" that matches the keyboard. Turn on the power and touch the keyboard with "Do Re Mi," and the singing voice of "Do Re Mi" by "Hatsune Miku" will resonate from the built-in speaker. Also, by pressing the control buttons "1 to 5," you can make her sing with the vowels "a to o." Furthermore, if you select lyrics in the "preset" mode, which sings with pre-prepared lyrics, anyone can make her sing a well-known song. Let's make her sing expressively by utilizing the vibrato and octave up/down functions.
