The Technics single-finger mode DOES work as Dave described, the same as Yamaha. Korg, and Roland method is more musically correct. I don't use the single finger mode, so it doesn't matter to me.
I got away from Technics because of the useless mic input and vocal harmony, plus the fact that they offer only a proprietary hard drive option that makes it several times too expensive.
Maybe the 7000 will address these issues. If not, the other companies already have.
Back to the topic--if you could find a midi file of the song, wouldn't it be very easy to use the internal converter to create your own style? I know the KN5000 did this, but I only played the 6K very briefly.
