The sequencer in the Kn7000 was far superior to the Korg Pa3x cant speak for the 4 x but I would assume there is not much difference between the two. It was way easier in step record, punch record. Korg cannot sequence like the Kn could back in 2002. Try one and you will see. This is my opinion Im sure there is other people that agree with me. I have said it many times Technics was ahead of its time.
