FLX4 to GVR6 ( Smart Fader request! )

Im a Lounge DJ and loving my FLX4. But I just upgraded to the GVR6 and I believe I made a mistake since I come to realize that the "Smart Fader" feature on my FLX4 is probably exclusive to this controller alone. So im hoping to have some sort of firmware upgrade to the GVR6/Rekordbox7 eventually that would also feature the Smart fader option. Anyway, great machines. Keep up the good work Pioneer/Alpha Theta Team!
