How do I setup midi with FC2?

I'm using the latest 2.6.8-1.521 kernel from fedora and I need to create edit and play midi files with programs like rosegarden but I haven been able to find a simple way to setup midi. I have tryed differen things with no luck, I have jack installed and rosegarden sayed it has found it and played the midi files but no sound comes out. Maybe someone can help set this up from start assunming that I have a fresh install of FC2.

 

 

Thanx for your help
