I am not a technician but I use this keyboard for a long time for models or pieces of skeletons dressed then acoustic (nbx samples http://klipmerei.free.fr ). The interface is rudimentary but qd we are accustomed, as all is fine. Lack panel to change settings sounds (the old, what buttons) easily. The keyboard is large and very pleasant - it was one of the rest of my selection criteria: physically as close to a piano. The object is heavy, not for the concerts. But at home ... I use it and have fun with always.
