Do you use Jack? if so, did you configure jack to expose hardware midi devices (a2jmidid -e)?

Try Mixbus with it's built-in ALSA backend (no jack) perhaps (Menu > Window > Audio/MIDI setup). That's a lot easier to get started with, and midi devices are directly supported there.

hi x42 if i used in terminal comand a2jmidid -e it's work and interfaces midi are recognized,but i must have open terminal

You can add an ampersand (&) to launch the tool in the background

Code:

a2jmidid -e &

Then you can close the terminal.

There are also various ways to automate this. One option is to use qjackctl's "after start-up" scripts (see also http://manual.ardour.org/setting-up-your...-on-linux/ ).

Things like this is what separates dedicated distros (e.g. AVLinux) from generic ones. I think KXStudio also has automatic setup for this, but I don't know. With Ubuntu you'll have do this setup yourself.

PS. Do you really need JACK? Are you using other JACK applications along with Mixbus and route audio between them? If not: Mixbus' ALSA backend is the way to go.

B)
Alsa2jack (MIDI):

Code:

a2jmidid

Setup >> Options >> [X] Run script after startup

Code:

sleep 5 && a2jmidid -e &

Setup >> Settings >> Parameters >> MIDI Drivers [none]
Setup >> Miscellaneous >> [ ] ([none]) Provide support for ALSA sequencer
