FOR SALE: Casio SK 1 keyboard sampler works great, but keyboard plays a1/2 step off ie C is B etc. (doesn`t effect sampler which is the only real reason to want one of these). Also, doesn`t work with batteries, but works great with a power supply. It`s small, awesome and I`m only selling because I have a SK 5 and don`t use it much. Available this week.
