Hello again---this time I have a question about entering chords in to the chord chart. I am attempting to enter the chord progressions from an arrangement of Bach's Well Tempered Clavier Prelude.

Most are accepted fine, but the following are not:
Gdim7, Adim7, G#dim7, A#dim7b11, A7sus4, G#dim7b9/A, A7sus4

Are there other ways that I should be entering these chords? I am a complete newbie to music composition and am following another person's chord chart.

Basic question, why is it that BIAB will not accept certain chord names? Does it have something to do with music composition or simply computer programming?

Thanks for you advice!
