The SL88 GRAND uses the best-graded hammer action keybed with Ivory Touch and wooden keys, to give you the natural feel of a well balanced grand piano. Each of the keys provides 3 contacts for superior performance. The results of this combination are simply amazing. From the slightest pianissimo up to the strongest fortissimo, the keys translate every nuance of your performance in an inspiring and truly superb way. With its compact profile, the SL88 GRAND is an extremely portable professional controller. Even with its high-end graded hammer action / wooden keyboard, it weighs less then 21 kilograms. The SL88 GRAND is studio and stage ready with a rugged full metal casing. Sculptured endcaps made of a highly resistant synthetic material help shield the premium TP40 wood keybed perfectly and provide a safe grip when handling and transporting.
