Initially sold for ¥65,000
Budget version of the bigger KX1 with the same concept: a remote MIDI keyboard controller with no sound engine but good performance controls. This time with small keys. Considering the similarity of features it may as well be the same circuit in a smaller shell.
Available in silver o black. Released in 1984 for 449£, the price was apparently cut down to 199£ by 1985.
