Hi John - thanks for that. I see that the 3 buttons you refer to set the chorus, and you can add an intro/outro as required. Its only that I happened upon the other button on the task bar first, which also sets repeats together with DC, DS etc, and found it a bit confusing to have 2 places to do essentially the same job. Anyhow this isnt really important.

On the other point though, I'm still not sure how I can tell whats actually going on. I got the idea of using part markers for drum fills on the preceding bar - thats great. But I dont see what else they denote. If, for example the first chorus is played by say the entire band, but 2nd chorus has sax solo, and say 3rd chorus is vibes - how can I see this. If the part markers do this, how do they indicate the specific changes?

Sorry if this seems a dumb question - and I've got plenty more!
