Thank you for your answer.

I'll go to the french forum when I need help. Now I don't need help I want to give my help.

I think BIAB is realy good for make a playback. I think BIAB may be good for write and print grids of chords.

Actually, I use Microsoft Word or Adobe Corel to write and print grids of chords. It's sad that BIAB can't do that properly. All my grids are in BIAB for playback but I must write again in other soft for prints them.

I suppose it's not very hard to do something best.
