How to test USB-midi

I use a Axiom air32 Mini USB keyboard. It works fine out of the box in Linux.
In freebsd :
/home/x root># dmesg -a | grep -i axiom
ugen0.4: <M-Audio Axiom A.I.R. Mini32> at usbus0
[20] uaudio0: <M-Audio Axiom A.I.R. Mini32, class 0/0, rev 1.10/1.40, addr 4> on usbus0
This looks good.
But then what , i.e. what can I do to test it and how ?
E.g. how to configure lmms for midi ? Is there another application I can use ? (ardour does not compile)
A qsynth/jack "tutorial" for freebsd ?
 
Please note, the keyboard only sends midi, notes pressed, i.e. no sound or usbaudio.
If I'm correct audacity is to record audio and cannot be used for usbmidi. (title of this thread)
Is there a vst or lv2 host application I can use ?
#pkg search lv2 | wc -l
gives 59. There might be something.
 
As a regular user i could start jackd &jack_umidi via :
Code: 
jackd -r -d oss -r44100 -n2 -w16 -C/dev/dsp1.5 -P/dev/dsp1.6 &
sleep 1
jack_umidi -d /dev/umidi0.0 -B &

The midi keyboard TX is show in the graph of qjackctl. Good.

Now I need something with gives a midi RX in qjackctl in order to connect.
brighton is not shown. Why ?
Nor hydrogen.Why ?
Nor lmms Why ?

ardour5 shows as only one up in qjackctl. After routing I have midi-in en audio-out. So that one works. Success. !!
Albeit only with the internal soundcard.

Note : a jack mixer app would be nice :(
