I just discovered the cool Playback view, and also that it actually
plays back chords (cool). And, of course, i immediately want more
options: is there, by chance, a way to control the way the chord is
played? Currently it's quite brief, the duration is like an eighth note,
it seems, in a 4/4 time sig. Would be nice to extend it, say, to the end
of measure OR until a new chord is stated.
