The original unit uses a proprietary analog IC manufactured by New Japan Radio that contains the core of the circuit. The Lumin is a reverse-engineered expansion of the circuit on that chip, but it should be stressed that it is not a clone, because the chip implementation is patented. A midrange knob has been added along with switches to set the frequencies of the Process and Contour knobs. -
