I must be missing something here.
amidi -l should list all midi out ports that are available to amidi, right?
No matter what i try with a2j and all of its variants (including j2a and
using the -e option) amidi -l never gives me any usable ports.
Same results as root.
Or should i be using the -L option to list the availabble ports? if yes,
how does that work? I cant figure it out. :-(
Another question: will a usb midi interface list the midi ports under alsa?
All help is appreciated!

Thanks guys!
I actually tried j2a but now i realise that i forgot the -e option to
expose the hw ports. Doh!
I'll give it another try tonight.
Thanks!

Maybe you should try the following command : aconnect -iol

It will, yes

It lists all ports implemented by an ALSA kernel driver. It is possible
to implement raw MIDI ports in software, but those are not listed.

ALSA's raw MIDI interface and sequencer interface are different.
Usually, you want to use the latter. Try "aplaymidi -l".

OK that seems to work fine, and the USB midi interface shows up when i run
amidi -l :-)
i created a virtual midi device that dumps incoming data in a terminal
window (using amidi -p virtual d), and connected the midi input port of the
USB interface to that virtual interface (in qjackctl)
then i connected my FX unit to the usb interface and configured the FX unit
so it sends midi messages
whenever i turn the 'preset select' knob on the FX unit the midi data shows
up in the terminal window
if i then send this midi data back tot the FX unit (using amidi -p
hw:2,0,0 -S 'C1 09') the unit jumps to the correct preset :-)
however, this does not work when jack is running. if jack is running i get
this message :
ALSA lib rawmidi_hw.c:233:(snd_rawmidi_hw_open) open /dev/snd/midiC2D0
failed: Device or resource busy
cannot open port "hw:2,0,0": Device or resource busy
looks like jack claims the device.
this is blocking for me since i need to have jack running for my audio
routing :-(
any ideas ?
