Hello,

I need help in understanding the guitar capo function.

For example: I input the chord Am into the chord-sheet. When I have the capo on the fret 3 then I expect the chord Cm

But biab gives me the chord F#m - why?

The chord display for Guitar (+12) does not really work for me. Nothing happens when I choose that option.

When I choose the capo on fret 9 then it works. Seems that I have to do any setting the the +12 is considered.(12-9 = 3).

It would be nice if someone could help me.


Thanks for help
