Hi, I'm trying to put the backup to a vocal sang alone with only a guitar. Repeatedly the tracks line up to the bar lines perfectly after some tweaking, but then after saving it it seems all the changes are lost when opening it again. Anyone know what the problem might be? Is there more than one possible cause? Does it regenerate the rhythm when opened?

Thanks.
