the other day, my wife and i were watching a movie on tv. after a while, due to the bad digital sync between video and audio, the voice of the characters was coming in with a lag. i said "look, it's going unsync" and my wife's reply was "what do you mean? i see nothing wrong"
it took another 15 minutes, while the unsync lag was increasing, until she finally noticed what i meant.

could be that for some of us, these little glitches (because they are just small unsyncs, few miliseconds of delays in timing, little bit too abrupt coming-in) are just passing unnoticed?

to me, i KNOW i had this problem (the relative volume of fills is indeed another issue, a different one) with smoothness of fills with my PA50. i noticed it when trying PA800 and PA2X. i notice it whenever, where ever occurs.

but maybe to some of us, again, it just passes unnoticed, somehow.

if that's the case, i can understand very well why there are some very defensive aproaches here. and that only increses the efforts from the other side to prove the obvious.

i think korg could solve this simply by fixing it! hehe
