No Sound from KMid

Hi guys, I am a novice when it comes to composing/performing music on a computer. But I understand that I need to understand MIDI in order to get anywhere. However, when I start KMid and open a midi file, I hear no sound even though the progress bar suggests that the application is playing through the file. Looking at settings, I see 5 MIDI devices: 1 x External MIDI 0 and 4 x Emu10k1 WaveTable Ports (0 - 3) All assigned as ALSA devices Also the MIDI map is set to /opt/kde3/share/apps/kmid/maps/gm.map. Can anyone tell me where to start to investigate this lack of sound further Many thanks -- Syl
