Hi Ian ,

Thanks for your interesting answer.I play guitar and
a Tyros 5 and I wanted the BIAB to help me to find
the right chords.
I don't mean Tonica , dominate and Subdominante
but sometimes you think it is the correct chord but
its not and that single wrong chord leads you on a complete
wrong track if you know what I mean

Anyway thanks for your opinion

Cheers
Udo
