The RADIAS-KB is the 4 octave keyboard that comes with the RADIAS. It is not a MIDI or powered keyboard, it uses a specific cable to interconnect to the RADIAS module or apparently the M3 module. This would be suitable for a user who purchased a RADIAS-R rack module and wishes that they had the dedicated keyboard to go with it. It could also be a smaller, traveling keyboard for someone who uses the M3 live, as my understanding is that they are compatible. Korg advertises their M3-61 as being able to have it's M3 module removed and allowing a RADIAS-R to be put in it's place, so the keyboard standard should be the same.
Keyboard is NOT sold by Korg separately, so if you bought the RADIAS module and wish to add the keyboard later, it is not possible unless you find one like this. Includes cable, all appropriate mounting hardware for the RADIAS module, original box and documentation, and accessory shelf. When the module is located to the far left or right of the keyboard, the accessory shelf can be installed for other gear or a laptop or whatever you may need.
(We have found that shipping to certain countries is cost prohibitive due to the maximum package size. This is in a large box (39" x 22" x 11") but will ship safely to the places that will allow a large box like this for reasonable rates).
