Cords play in unison with mellidy

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a composition with 2 tracks one track holds cords that will be played 
once per bar, the second has individual quarter notes.

2. play composition.

What is the expected output? What do you see instead?

What is expected is that the cords will be held for their full whole note 
duration while the quarter notes play at a different speed.

What I see is that the cords are repeatedly played in time with the quarter 
notes.

What version of the product are you using? On what operating system?
First observed with 4.2.3 than I repeated it with a 4.3.0 version downloaded 
with hg.

Please provide any additional information below.
attached is the source that I used. Please note that I made the one line change 
to add pulseaudio to the allowed drivers so that I can get audio output in 
Ubuntu. 

I seem to have tracked the problem down to the play_Bars function in the 
Sequencer class. But I haven't digested the code enough to understand why it's 
doing what I notice. This may also be an issue with understanding how to 
properly put together a composition.
