To answer my own dayum question (since yall were sooooo helpful

). If you have a Biostar M7VKQ and need to load MPU-401 legacy midi...you CAN'T do it in the operating system by "Adding Hardware" under Windows. All you get is conflicts. You'll need to go into BIOS at start up under Integrated Peripherals and enable Legacy Audio, enable Soundblaster and enable MPU-401. You can then connect your music keyboard to the gameport and run your synth app.
