after diggin through the event inspector i did see a fair amount of note drift later in some of the tracks - lining up more than 100 or so ticks off beat in either direction. not sure what this was due to.... my guess was recording audio in another application at a different sample rate than sonar was running at, so i'll take a look at that. the pure data program I am using can be downloaded here:
