Begin with a Band-In-A-Box file that contains the chords and melody of a tune you wish to export to a music notation program.
In step 5, ChordBuilder reads the exported score, parses the chord data from the bass and piano.
In step 1, when you load the export style to play with a tune that you want to export, you must:
In step 3, tell Finale to import the SMF file by quantizing to sixteenth note resolution and to space notes evenly in every beat to neutralize some of the tune's original input interpretation.
ChordBuilder (step 5) is a command-line program with only one command line parameter. You specify the name and not the extension of the MusicXML file that ChordBuilder reads. The extension has to be .xml. ChordBuilder builds a file with the same name and a [1] suffix. So indiana.xml becomes indiana[1].xml.
ChordBuilder also reads the SMF file that Band-In-A-Box exported. ChordBuilder expects that file to have the same filename. ChordBuilder has to read that file to extract the tune's title.
