Apple Logic Pro /LogicExpress Discussion

I  recorded a long audio (wav)  file in Logic, chopped it up into  
regions, and saved the regions as wav files.  The bwav protocol is  
time-stamped, so I used a program called BwavLister to read the  
metadata and list the start times (in SMPTE time code) for each file.

The problem is that the start times listed in BwavLister are  
different from those shown on the logic smpte ruler, both in arrange  
and sample edit.  I tried recording both at 30fps and 29.7fps, with  
similar discrepant results.

Can anyone think why Logic would not jive with the stamped metadata?

Thanks,

Gregory

This was clearly a captivating question, so I will answer it  
myself.   Logic's timeline is on a MIDI time clock, which for some  
bizarre reason uses 80 sub-frames per frame, compared to smpte which  
uses 100 sub-frames per frame.    So the timestamp on the bwav files  
is in the 100sub frame format, and the time listing in the event  
window is in the 80 sub-frame format.  Annoying, but at least it's  
not a bug.
