not sure what might be wrong but do you set the right key? not sure BIAB can work out the key - if it can ignore this message but if the melodies are in a particular key and BIAB chooses the wrong one it might sound 'off'.
and make sure BIAB is set to simple arrangements and no 'embellished 'chords
