Hi all and thank you for your immediate responses.
In the end what I was looking for was not the "midi through port" but a virtual midi port.snd-virmidi midi_devs=1 index=5
$ amidi -l
Dir Device Name
Dir Device Name
..... (other devices) .....
IO hw:5,0 Virtual Raw MIDI (16 subdevices)
and at the same time it would show up in jack's "midi" tab
then I could simply use it as
amidi -phw:5,0 -S <hexbytes>
and the midi msg was surely enough sent correctly to the HW controller.
Thank you for your help!
I hope this helps others as well

Hi Athanasios,
amidi uses ALSA hardware ports, not ALSA SEQuencer ports. On my system
MIDI thru doesn't show up under those. You can list them with:
amidi -l
or look at:
/proc/asound/cards
Since you're sending MIDI CCs and no SysEx you can use a tool that
supports ALSA SEQ ports.
If your CCs and values are always the same - or just a few setups - you
could put them inside a MIDI file and then use aplaymidi. Otherwise
there is midish a commandline tool, that supports its own bash-like
scripting. It wouldn't be too hard to set something like this up.
http://www.midish.org
If Python or other scripting languages are an option, there are some
packages for these languages which support ALSASEQ I/O. If midish looks
promising, but too much work for a start, I could help.
HTH.
Best wishes,
Jeanette
