track location information

Hello,

I want to write an AU plugin that produces an effect dependent on the location in the audio track; hence, I need to have access to the track location information.

Here are the possible ways of addressing this that I have read about:

1) use function:  CallHostTransportState
But this doesn't seem to work:  parameter outCurrentSampleInTimeLine is always 0.
Perhaps GarageBand hasn't implemented this function?  Any experience with this function (perhaps with different hosts)?

2) write 'aumf' plugin, and use MIDI info to get location-specific info.
This is potentially more work than I want, since there doesn't seem to be a lot of documentation about implementing this type of plugin.
Also, I don't want to be forced to use midi data as the time-dependent control info.

Perhaps there are other approaches as well.  What is the easiest solution?
thanks,
