>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) Roman > ============= > Panagiotis Melidis > > http://www.larrygus.com > http://facebook.com/larrygus > http://twitter.com/larrygus > http://larrygus.tumblr.com > > > On Tue, Jan 15, 2013 at 3:26 PM, Martin Peach > <[email protected]> wrote: > There is no timestamp in the MIDI spec.
