MMA has a number of different ways to gather and play the various notes in a chord. The following little script will cycle though them using the same pattern/sequence and chords. As an experiment, you might want to change the chords (try 9th, 11ths, etc) and the KeySig. Interesting things happen :)
/// Simple script to demo all the various
/// voicing mode options. Here we create a
/// simple CHORD pattern that we play with the
/// same chords in each mode.
