[LAU] how can I send a midi command from bash through jack to my HW controller?

Hi all, I have a BCR2000 and would like to use a script to set some values on these knobs and buttons. amidi should be able to help me do that but I somehow cannot properly set the name of the port in order to use it. Note, jackd server is up and running and then I also use the "aj2midid" midi bridge to populate hw and software midi ports in jack, So even though I thought this would be easy , I am stuck somewhere. The command I am trying to use is amidi -p"14:0" -S <3x bytes depicting the midi CC command> now port "14" SHOULD be the "Midi Through port as it appears in qjackctl's "midi" tab. I got it from $ aconnect -i -o client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' client 14: 'Midi Through' [type=kernel] 0 'Midi Through Port-0' client 16: 'TerraTec DMX6Fire' [type=kernel] 0 'MIDI-Front DMX6fire 0' 32 'Wavetable DMX6fire 0' client 24: 'Hoontech SoundTrack Audio DSP24' [type=kernel] 0 'MIDI-1 Hoontech/STA DSP24 2' 32 'MIDI-2 Hoontech/STA DSP24 2' client 28: 'Hoontech SoundTrack Audio DSP24' [type=kernel] 0 'MIDI-1 Hoontech/STA DSP24 3' 32 'MIDI-2 Hoontech/STA DSP24 3' client 32: 'BCR2000' [type=kernel] 0 'BCR2000 MIDI 1 ' 1 'BCR2000 MIDI 2 ' 2 'BCR2000 MIDI 3 ' but running "amidi -p14:0 -S <hexbytes>" returns cannot open port "14:0": No such file or directory What am I doing wrong? thank you in advance for your help
