You're welcome, Ian.

I hit the snooze button a few times and got into work a bit late, but I'll make it up later. I'm not tired now but will be this afternoon; that's when it catches up with me.

I, too, find the manual and the Help files a bit lacking, but I know how hard it is to write a great users guide. But I'll tell you what's remarkably good: the tips that pop up when you hover your mouse pointer over an item. They are fairly robust and often provide enough info to obviate a trip to the Help files or manual. The PGM software dudes who are responsible for the user interface are to be commended for taking the time to work those link tags into the program. Very convenient, I think, and greatly increases the usability of BIAB.

If I stumble across anything like the soloist dominant thing for chord subs, I'll let you know, but I infer from Matt's comment that it doesn't exist, and he would know. (He was obviously being polite.)
