cool, thanks.
better than a ifdef, a startup flag!

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...)

my pd usage usually imply sending and receiving as fast as possible.
sending delay usually annoy me.

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). But I have to admit I've never treated this as a high
priority (which one might take as an implied value judgement about MIDI).

with MIDI, Pd doesn't do any buffering and no synchronisation to some
external clock is done, so messages appear in bursts which you notice
as a inaccurate timing.
There is 1 strange thing however : pd did some kind of buffering with midi, in
order to synchronise with audio out.
if you configure 100ms audio latency, then a midi loop will be between 100 and
105ms.
with 10ms audio buffer out, the midi loop is between 10 and 15ms.
but this buffer should not change anything on timing except adding latency.
