I believe if you edit s_midi.c and change: if (midi_outqueue[midi_outtail].q_time <= midirealtime)
to if (1) and if (midi_inqueue[midi_intail].q_time <= logicaltime) also to if (1) that will make it fast-as-possible. The queueing code should probably be surrounded by an ifdef to make this easier (perhaps someday...) cheers M On Tue, Nov 27, 2012 at 06:23:15PM +0100, Cyrille Henry wrote: > Is there a way to bypass all of this? > my pd usage usually imply sending and receiving as fast as possible. > sending delay usually annoy me. > cheers > c > > > Le 27/11/2012 18:06, Miller Puckette a écrit : > >Pd tries to time-stamp MIDI on input and tries to delay sending MIDI output > >until the correct time; but Pd's accuracy in doing this is limited by the > >fact that it can't input or output MIID while it is either sleeping or > >running > >(only when the scheduler polls for what-to-do-next after either a task or a > >sleep has finished.) > > > >It would be more accurate for Pd to rely on either software interrupts or > >even > >better on some underlying OS time-tagging mechanism (for instance by > >exploiting > >whatever portmidi does).
