but if you have the right cables or headphones then its no problem.

Light as a feather - 3.4 Kgs only, I can play it on my lap, carry it anywhere, use any ready made headphone, use the bevy of adapters when I really need it for sound output, very good key feel, solid number of controllers and pads, can be used for automation with software and comes with a solid selection of free software including Reason limited, plugins from Garageband and the editor software for every parameter that can be saved in "scenes" which are essentially program parameter settings snapshots

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
