When i had my Pa800 if you had pads running during a style & you hit an ending.....even after the ending stopped the PAD would keep playing for a few beats which was very annoying....you had to shut the pad off before the ending was pushed Grrrrrrrr!
I hope KORG fixed that now. the ending should cancel the pad when executed.
Apparently they did, because the pads stop playing after the endings on my PA2X.
