Mac: The durations were "5" but multiple notes with that duration and the exact same start times. I will keep an eye out for possible "0" duations, so thanks for that insight! In any event (no MIDI pun intended), I discovered it was not only the structure of the file and the way that the playback engine of PT handled it, but also something in my PTW.INI and PTPA.CFG files, subjects of a deletion suggestion from product support. IT'S REALLY NICE TO KNOW THAT PG PRODUCT SUPPORT, ALONG WITH USERS ON THIS BOARD, HANG IN THERE WITH YOU!

I just sent this to PGsupport:

BTW, your suggestion to delete the PTW.INI and PTPA.CFG files must have played a part in the "dropped-drumbeats" solution, even though just deleting the files had no effect. After hitting upon the Quantize-duration fix for the problem, I later restored my old ini and cfg files and the dropped-beat problem reappeared. Then, as soon as I deleted the ini and cfg files and restarted PTPA12, the problem again went away. It appears that the combination of the two steps was necessary to solve the problem.

I'm attaching the original (problematic?) ini and cfg files, just in case you want to exam them.

Thanks again,
Stan
