This is a MIDI keyboard from CME, a rising star manufacturer known for releasing WIDI (wireless MIDI) keyboards and compact MIDI controllers. It has semi-weighted keys that feel good to play, and with 49 keys, it's a good size for a sub-keyboard or a DTM desk. No accessories included. No box. A carrying bag is included. The original product did not include a Japanese instruction manual. It has octave change (+- keys) and key transpose (SHIFT and +- keys) functions. Only the main unit is included, no accessories. The product will be wrapped in air cap and shipped. The CME M-key is not often seen on the market, so if you're looking for one, don't miss this opportunity.
