i am working on osx, ver 10.8.2

i am sending noteout messages from PD over to Ableton Live via the IAC driver, but after a certain point ableton live ignores the messages, and this has to do with the fact that live itself is getting confused by the timestamps.

on the ableton forums people found that the solution is to add the timestamp with the midi message, and some people managed to achieve it for C++ and Python as explained in those two posts;

https://forum.ableton.com/viewtopic.php?p=1347051#p1347051

so, i am struggling to find a way to change the timestamp of a noteout message but i can't do it. 

any ideas?

hope i was clear enough :)
