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
