This is what I usually would like to do with BB.

Take a jazz standard and write it out in the standard key in BB.

Then, since I am a French Horn player, I want to transpose the entire piece, Melody and Chords to the proper key for me to play in.

When I am on the Notation page and I go to OPT button, I cannot seem to transpose the Entire piece Melody and chords to the right key.

As mentioned earlier, when I want to transpose One semitone, it does a Whole Step which equals 2 semitones. Why is this happening? It seems illogical and flat out wrong what BB is doing, which leads me to the conclusion that it may be a Bug.

Thanks again Jeff
