Hi, I have a problem using IDirectMusicThru in conjunction with the default port (MS Synthesizer). I don''t hear a thing. All other port (like the Creative Midi Synth [620]) of my sound card work no problem. I wonder if I need to download the dls instruments manually to the output port, but haven''t found a clue in the SDK-help or on the web. Seems like nobody did play his keyboard with DirectMusic before... Thanks in advance, I''m really stuck... Christopher
