You stated you're using a windowproc? How are you doing this with an MFC window?

LRESULT CYSPController1Dlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam) <br />
{<br />
    ubyt    ubMidiData;<br />
    switch( message ) {<br />

Have you tried getting the message in your maindialog class using the message map?
