sx 3 audio drops at end of loop

[filterfreak]

ever since ive had my sx3 i get audio drops at the end of a MIDI loop , it only happens in loop mode , if i let the track play all the way through its fine but as soon as i loop the track i loose the last 3 bars of the sound , has anyone else had this problem , its really frustrating as you can't sample or record anything from midi in loop mode , any idea's anyone ?

all sorted just incase anyone else has the problem which has bugged me for a long time , go to preferences ,go to midi and in chase events unclick program change as its the program change trying to reset its self for the start of the loop , sorted and well happy !
