FWIW, this already fails:

START_TEST(midi)
{
     MMRESULT rc;
     HMIDIOUT hm;

     rc = midiOutOpen(&hm, 1, 0, 0, CALLBACK_NULL);
     ok(!rc, "midiOutOpen(dev=%d) rc=%s\n", 1, mmsys_error(rc));
     rc = midiOutReset(hm);
     ok(!rc, "midiOutReset rc=%s\n", mmsys_error(rc));
     rc = midiOutClose(hm);
     ok(!rc, "midiOutClose rc=%s\n", mmsys_error(rc));
}

it hangs (doesn't return) in the midiOutReset() call.
