How to play midi and update graphics at the same time?

hello

I want to begin playing a midi file and thenimmediately while the music is still playing I want to update the screen, for ex. panel.update();

It now seems that that whole screen freezes until the music has finished. How can I simultaneously update UI and play midi. Please help. Thanx!
