| hi there,
i have sent sysex with puredata for some years now, and i never had any problems, even with large chunks. i have used attached abstraction to send sysex, maybe it helps?
midi IS a serial protocol, so it is perfectly valid to send one byte at a time at least over din midi. in fact i am doing that with arduinos all the time. (usb midi is a different beast)
do the “special” midiout noteon and noteoff messages work when a synthmodule or similar is connected?

Description: Binary data
Hi Miller, yap I'm using ALSA.
btw, I had a look at the source code (I want to clarify I'm not a
C programmer :) ) and from what I found in x_midi.c and s_midi.c,
it kind of make sense that [midiout] returns 1 byte at time. it seems to me we're missing a way to detect outgoing sysex
messages (maybe having a dedicated object could help), so there's
no way to collect a sysex and send it out in one go (ie having an
array to return). I apologize for my trivial description of
the "problem", but this is what I think is causing this
behaviour.
cheers, Mario

Hi Mario -
Perhaps you said this in the previous message which I missed... are you
using ALSA MIDI system or OSS?
MIDI support has always been a problem in Pd... largely because I don't have
a lot of experience with it.
cheers

Hi,
I ran few more tests on Linux trying to understand what's going on with
[midiout] and sysex messages.
I discovered that it's not just about sysex. I'm monitoring MIDI from Pd
with /KMidimon /and /GMIDImonitor/, and I noticed that also sending Note On
messages with [midiout] seems to be in some way different then sending the
same message using [noteout].
when Note On is sent using [midiout], this will spit single bytes that are
recognized as single byte sysex messages by the MIDI monitors!!!!!
has anyone ever experienced the same?
cheers,
Mario
