there's actually 3 people (or probably more). Pareo mostly plays the piano and synth sounds. Chu2 handles some of it, plays the DJ mixer and the samples like dubstep etc. And at the back WHO does the backing tracks, that's why Chu2 can move around. For example: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oooMGWENwIs.html Take a look at 6:05 on this link, while the synth part is playing, Pareo is playing her front keys which she is using only for acoustic/grand piano sound. That proves that Pareo is not the only one who plays the lead sounds, but Chu2 or the guy at the back as well.
