I have my melody instrument set to guitar. Using BIAB 2011. When I open the Guitar Window and click play, the guitar sound (and fingering) is an octave higher than what would be played by a guitarist reading the piece, i.e., the piece is played at concert pitch. The problem is that guitar is transposed up an octave (sounds an octave lower than written). How can I get BIAB to play the guitar part at the correct pitch? Is there a special "guitar" setting.
