[PD] changing timestamp of noteout midi message

[Panagiotis Melidis]

hello all.

i revive this thread to ask you if there is any way that i can edit a
noteout message _after_ it leaves PD, in order to add the desired
timestamp. midipipe in the end didn't work, so i am looking for
alternatives, to no avail so far.
