Time will show they say ....

But,
I'm wondering about if this is more a audio "playback-karaokemachine" with arranger features, or is it a well equiped Arrangerkeyboard with audio playback features.....

Also noticed at the picture that the SD40 have buttons for 4 variations, 1 fill, 1 break and 1 start button. Where are the rest of the controls to f.ie. intro, more filltypes etc. hidden?
Have to take another look after cleaned my glasses.
