UBUNTUSTUDIO and LMMS problem

[giulio]

I have problem with configuration with LMMS
I would like to use a expander with a usb midi cable.
In other software the midi is working and it's easy to configure. For example in Rosegarden and in Tuxguitar.
But in Lmms I tried many times but without no result.
Somebody may give some little help?
I add some information about my problem.

if I write
aplaymidi -l

I will have this information
Port Client name Port name
14:0 Midi Through Midi Through Port-0
20:0 CH345 CH345 MIDI 1
128:0 TiMidity TiMidity port 0
128:1 TiMidity TiMidity port 1
128:2 TiMidity TiMidity port 2
128:3 TiMidity TiMidity port 3

and if I write:
aplaymidi -p20:0 song.mid
I have the midi working


Ok, now LMMS works, I understood how to do, Just it need to repeat setting midi for each single track,

No need to replay this post.
