Thanks Clinton. Yes, band in a box don’t have the cracking problem and also it has a button to repeat choirs. But the sound quality is not the best, at least not here and without buying extra packages. So my ‘solution’ has been to use real band, and the copy paste function with hundred line repeats. It’s just that it requires good patience while copying, changing style or tempo. So one day I will find time to investigate your idea and see if its an offending note or just the normal start function.
