still makes no sense to me! maybe if the documentation explained how to use the capo feature that would help or perhaps someone here can explain it to me. but I feel it would still be counter intuitive because guitarists already know how a capo works!

1) I pick up my guitar and play a C shape and I hear a C chord
2) I place a capo at the 4th fret and play a C shape and I hear an E chord

1) in BIAB I enter a C and I hear a C chord (so far so good!)
2) in BIAB I place a capo at 4th fret but now the chord displayed changes to Ab and I still hear a C chord...WTH?

I don't get this at all! I would prefer it not change the displayed chord at all and instead change the sound like capos work on a guitar. But even if that is not possible why does it display an Ab and not an E when I start with a C and then capo to 4th fret like it would on a guitar?

But maybe it's just me! Admittedly I am no music expert.
