Found the user manual here - http://www.madeffects.com/ekmps/shops/m ... -pair-750-[2]-818-p.jpg By reading the user manual i found that red bar next to the BPM is called the memory bucket. Sounds as if the red bars are a buffer status, so when the bars are full it means their is a 12 second buffer (6 bars times 2 seconds). The song is pausing/cutting out when the bar gets down as their isn't enough buffer for the song to keep playing. Never used one of these players myself, but i would suggest letting the buffer load up fully before you start to play the track, to ensure the buffer is as full as it can be before you start playing it. Another reason it could be happening if you are trying to use alot of extra effects (using alot of the memory banks and using them constantly, using the effects all the time, etc.) it could be beyond what that player can handle, so if you see the buffer start to lower, stop utilising the effects until the buffer loads up at least.
