I don't think there is a standard 'Template' as it would need to cover every chord Biab can use. In my brief attempt to create a user track. I found that if i used a chord in a tune that was NOT in my user track tune. BiaB didn't play anything. So long as you are aware of this then it isn't to hard to set up a 'template track' of your own using all the chords that you normally use in the music you write.

I just started with simple 251's eg Dm7 G7 Cmaj7, then 25's eg Dm7 G7
one chord per bar. by using the transpose function and copy and paste you can very quicly run these chords through quite a few different Keys. Then just add any alterations to the chords you might want eg a b5 or#5 to the G7 chord and b5 to the minor. Use copy and paste and tanspose again and very soon you can have a template over 100bars long. This really is just scratching the surface with user realtracks.
