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.

thanks a lot for your replies!!
for now, i found a solution, which is this little application called MidiPipe http://subtlesoft.square7.net/SubtleSoft/MidiPipe.html, which helps you modify the midi messages, and i just added a sort of 10ms delay, which in turn forces the message to carry the timestamp.

thanks a lot for your answer martin!
so in that case, is there any way to modify the noteout object in order to add a timestamp? otherwise i should find a way to add the timestamp _after_ the message is sent from noteout, right?
From what I know - and probably what Martin meant before - there is no way to specify a timestamp in MIDI as the MIDI protocol simply has no timestamp defined. When timestamps are involved in your problem, they most likely are not implemented on the MIDI level, but somewhere else.
As there are no timestamps in MIDI, it is unlikely that your problem can be solved by hacking [noteout].
The concept of timestamps in your problem seems specific to the IAC bus you mentioned. In the link you posted I read:
"A hacky workaround would be to route the MIDI bus to an intermediate program that echoes the MIDI packets to another IAC bus but adds timestamps."
Have you tried that? (I must say I don't know anything about IAC bus nor any specifics about MIDI in OS X)

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 :) ============= Panagiotis Melidis http://www.larrygus.com http://facebook.com/larrygus http://twitter.com/larrygus http://larrygus.tumblr.com _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
