Diki I did not say I would not or never have used a fill on other than the top of the bar! Just stating that when I tried to emulate the problem AJ raised it did not happen for me when the fill is activated on the beat, any beat 1,2,3,4!!. If you "Randomly" activate (In the cracks) you will get the glitch !! For whatever reason it is not a problem for me!! I can understand it maybe a problem for others and yes this is unique to "Korg" arrangers.
