Its VERY BASIC on some level , not that deep but its the tone and rather low fi nature of its waveforms and their unioque character your buying here.

This synth Stinks of Detroit techno and warp records idm , really i own most of the kawa / ensoniq and casio fz machines used in that genre aswell as the fm / dx synths and this ones unique , it somehow had this glassy pad tone i cnat get off any other synth , even the k1 etc .....i really recommend this if you after really nice chord / pad tones and smooth basses etc , it is cheap but it is utterly unique in its character and 110% detroit / deep hiuse / jazz techno .Very good for idm pads . . . its my favorite pad synth when i want that moody idm / detroit sound.

With minimal editing facilities, the Spectra barely qualifies as a synth, but that's not the why anyone would buy it. It's simply the only five-octave keyboard you can strap on and wander about with. (Admittedly it was a bit dumb of Kawai not to make it battery-powered, so some kind of extension lead on the wall-wart is a must...)

As for the keys being a bit flimsy, well, yes, they click a bit - but the whole point is that the thing is light enough to wear! For a synth that's over 15 years old, the keys seem to have survived just fine, so they must be tougher than they look or feel.

If you want a 5-octave MIDI controller you can wear, get a Spectra. if you have anything else in mind, don't.

The sounds are awful! The Pianos are too toy-like, and the strings almost hiss!

Not one to go for, really!

Try the K1, or the K4; they are much better!
