Regarding power supply, the best feature about this unit given the size and specs -- its runs off my phone power bank (the phone itself is a power bank) over usb

I'm not going to list the wonderful features

OK, I was really intrigued by this unit, so much so that I paid extra to order one from Japan, before they were readily available in the U.S.This unit has loads of great features, and is very portable

mine came yesterday,im blown away at what this can do and by the sounds it has,as well as the extras like gongs,bells,wind ,thunder,birds,its packed with stuff,the keys are great to play,if your thinking about buying one,i say buy it

You can also use it to play scales and is good for some kinds of ambient or aleatoric music as well as for glissandos

Its primarily a composers and performers tool as well as for ideas generation and arrangements tryouts in the studio
