Check out how Ningen Gakki works! (I suggest you watch it until the end of the video.
Keep your eye on FKO)
What is Ningen Gakki??
Takara Tomy is at it again! Ningen Gakki turns human body parts into an
instrument. With you touching the Ningen Gakki, various sound and melody
comes out of Ningen Gakki when somebody else touches anywhere on your body
(skin). For the Drum Mode, you and 3 other people can start jamming as
it creates bass sound, snare sound, hi hat sound, tom sounds (high and
low), and 2 different cymbal sounds. If you practice enough, you can create
your group's own drum solo!
The Performance Mode allows you to play 10 different melody (songs). All
you need to do is select the song you want to play, and touch the other
people that you are playing with for every sound of the song. If you play
it correctly, it will even applaud for your performance. On the other hand,
it will start booing you if you do not play the song right. You can even
create vibrato depending on how you touch your partners!
