[LAU] how to start in the middle of a song in seq24

Hi, I'm using seq24 + soundfonts to practise jazz charts; I play each part in seq24, record it, loop it, and practise the different sections. I have been trying to use the Song Editor to arrange the song in sections according to the chart, then loop over certain sections that I want to focus on. The problem I am having is that, when I loop, I have to start at the beginning every time. Once the playhead gets to the loop, it loops the section I want, but this is sort of wasting practice time, as I have to start from the beginning every time I stop. So, long story short, is there a way to start in the middle of the song, or start at the beginning of the loop? regards, Rich
