Hi Miller,
thanks for the suggestion. Glad to hear there's a "workaround"! I'll try
this before on my Linux machine, so on Monday I can do the same with the
computer I have at work.
it would be great to have this as an option, for example, in
Preferences. I know probably it's a kind of niche feature, but this
would help a lot in dealing with sysex stuff.
cheers,
Mario

If you don't mind recompiling Pd, you can control the MIDI queue size
by editing this line in s_midi.c:
#define MIDIQSIZE 1024
I think it has to be a power of 2. You could make it 0x100000, for instance
(a million-ish).
To easily recompile Pd on a Mac, install the developer package (compiler
chain which I think is now called Xcode), open a shell, Cd to
Pd-x.app/Contents/Resources/src, edit s_midi.c, and type "make".
cheers

Hi All,
I'm trying to record a bunch of sysex received from and external machine
(sequencer/synthesizer).
I tried using both [midiin] and [sysexin], and I've always got the same
result: "MIDI timing FIFO overflowed" printed on the console, and a lot of
data missing (I'm sure about that, cause I know how big the stored file
should be, and also cause it's an external flash dump, so I should be able
to send back this sysex to the unit, but when I do this the unit gets
stuck).
I know for sure that the unit is sending sysex at a really fast rate, as
fast as it can (at the moment I don't remember how fast exactly, but I can
double check).
is there a way to setup a kind of buffer? something that allows you to
accumulate this data before they pass through [midiin] or [sysex].
I'd like to give some context (and believe me, I don't really like this kind
of comparisons, at all!).
as it's something I'm doing for work reasons, I had to try using MaxMSP and
I ended up with something that works. the only thing I had to do is changing
the parameter related to the "scheduler time interval". so, what happens
there is the following: Unit sends these messages as fast as it can, MaxMSP
receives and accumulates all the messages, and pass them to the patch one
after another at a slower rate then the Unit's one.
do we have something similar on Pd?
cheers,
Mario
