1- Problem
There is lag/delay/stops when playing over midi.

2- Solution
This site is a very good resource: http://wiki.linuxmusicians.com/doku.php ... figuration
I applied most of the directives and did not experienced lags anymore, even with no 'real' realtime kernel.
The Perl script realtimeconfigquickscan linked there helped a lot too.
For each problematic aspect it finds about timing, it gives a link to the solution.
Not all suggested parameters apply for all, but for me it solved the lag/delay problem when recording and playing back.

Hope this will help someone with same kind of problem.
