I believe the memory is set to store track information for about 30min or so. After that the memory is wiped and the track starts at the beginning. Yeah I know it sucks when your trying to listen to one of those long ass Armin van Buuren mixes.
You can detect right away those that are going to be shaky, and that will fall behind and those that are very hungry, and that hunger you will have to develop. You gotta create a goal for yourself whatever that may be, a short term goal and a long term goal and you gotta go after that. And if you donít see it, and if you donít believe it, who else will?
