ubuntu lmms midi keyboard not work

[padaboo]

I Have:
1. Installed lmms.
2. qJack3
3. a2jmidid -e
4. ALSA Drivers
5. Nektar impakt lx 61

in lmms settings audio interface - jack

in midi setting a can't change setting - Dummy (midi not support)

Jack settings:

Jack audio

Jack alsa

Jack midi

aconnect -o

client 14: 'Midi Through' [type=kernel]
0 'Midi Through Port-0'
client 20: 'IMPACT LX61' [type=kernel]
0 'IMPACT LX61 MIDI 1'
client 24: 'Steinberg UR22mkII' [type=kernel]
0 'Steinberg UR22mkII MIDI 1'



In audio settings: settings->midi->input
should be: settings->midi->input->impact lx 61

Troubles:
1. lmms not see device.
2. lmms not change settings->midi->interface
