Hi Pedro,
I've had to examine MIDI bytes myself. I do not know of an application
that dumps the raw MIDI bytes. Never looked for one so I'm not sure if
it exists.
The way I did it was by using RTMidi.
http://www.music.mcgill.ca/~gary/rtmidi/
It's fairly easy to do this. Check out the section for MIDI Input with
User Callback.
Should be easy to enough to follow and compile.
Note that you would have to change this line:
midiin->ignoreTypes( false, false, false );
to
midiin->ignoreTypes( true, true, true );
Read the docs for the correct flags if you ONLY want timing info.
BTW, here's my LAU post for the small midi remapper I wrote:

You might find it useful. If you need further help I'd be glad to be of
assistance. However, I should get back to work. ;-)

Hi Pedro :)
Okay, this seems not to include information about any timer, but I could
compare it with the information from Kmidimon, that will be okay.
If I will add a dump, maybe buy using an array and if I will include
some timer information, do I have to include any other headers?
I think I can add some program code myself, that might be not good, but
good enough for my needs and maybe a step to bear down my concerns about
C/C++ and the structure of Linux.
I have to admit that I don't like Linux for audio very much, but because
it seems to be the only FOSS OS that seriously can do audio, I have no
choice, I have to use it. I more less like closed source codes and
expensive or cracked software for audio, so I have to become more
familiar with Linux, if I like to do this or not.
;)
Thanx again,
Ralf

Nobody has answered yet?
yep, thank you for your reply.
I'm
new to the list and I'm not a Linux audio developer. I was a coder
for C64 MIDI and audio, programming in Assembler, I have less knowledge
about C/C++.
Because I have to do some research, e.g. because of strange behaviour of
MTC, I need a MIDI monitor, that shows MIDI bytes instead of an
interpretation of the MIDI events, like it's done by gmidimonitor and
kmidimon.
You can try the utility "amidi" (from the alsa-utils package) with the --dump
option. See http://www.linuxmanpages.com/man1/amidi.1.php
Can
anybody help me to get such a MIDI monitor, maybe by simply writing me
how to compile the rwamidi example?
edit the source, change the line:
#include "../include/asoundlib.h"
by
#include <alsa/asoundlib.h>
compile it with this command:
$ gcc -o rawmidi -lasound rawmidi.c
You need the -devel version of the alsa library package installed first, and
the GCC compiler.
