HI...the pa800 will trigger just the normal fill 1 or 2 or break if set up that way,I don't use it I use the pedel,I had a kn3000 and that was so long ago, and I don't recall the technics 6500 having that feature.I am far from being an expert with these key boards learning every day,and having lots of fun,I really did enjoy the technics, I did not wan't to put any more time into this keyboard to have it break down and have to start all over again and it was quite some time before I began liking the Korg,now that I understand the Korg more I find it to be just great,I still think the sounds on the technics were the best////Paula
