Im still waiting for someone to make a flexible interchangable feature arranger / workstation KB.....that you could buy/add/remove modules for different purposes AS NEEDED.....eg: CD rec/Mp3/Voc Harmony/Sound boards/Sampling/ etc....this would make each unit "YOUR OWN" & mix and match components, removing modules to lighten up the rig for gigging, plug in modules in a studio for recording, editing etc...plus if they KEEP making different modules for MANY different purposes you wouldnt have to keep buying a new KB ...just buy the modules/plugin boards you need for your purposes.....am I Rambling......Dreaming......or Making Sense
