It sounds like a split second gap in the music. I checked my drive-it does not need to be defragged. I run windows xp professional. The hiccups occur approx. every 6 or so bars, but it is not completely consistent.
I might have heard this problem before but recordings I made 6 months ago didn't have this gap in them.

I just picked a style (JIN_Orl2 VintJ New Orleans2) and plugged in the chords. It is saved on my hard drive as a sgu file if that makes a difference. Like I said, I am not a frequent use of band in a box.

Thanks again
