Please check whether the patch attached to bug #28388 helps.
In addition, you may try this hack:
diff --git a/dlls/winmm/winmm.c b/dlls/winmm/winmm.c
index 9996f11..4260e09 100644

 static BOOL MMSYSTEM_MidiStream_PostMessage(WINE_MIDIStream* lpMidiStrm, WORD
m
 {
     if (PostThreadMessageA(lpMidiStrm->dwThreadID, msg, pmt1, pmt2)) {
-        MsgWaitForMultipleObjects( 1, &lpMidiStrm->hEvent, FALSE, INFINITE, 0
);
+       if (GetCurrentThreadId() != lpMidiStrm->dwThreadID)
+           MsgWaitForMultipleObjects( 1, &lpMidiStrm->hEvent, FALSE, INFINITE,
0 );
     } else {
        ERR("bad PostThreadMessageA\n");
        return FALSE;

Your log shows that the app calls midiOutUnprepareHeader and finally
midiStreamClose from within a function callback.  Wine hangs because it's
waiting for an event that is to be delivered by the player thread on which the
callback executes.  This remembers bug #3930, comment #35.

If Wine's midiStream messaging as seen in MidiStream_PostMessage were changed
not to wait for itself and solely queue the message, this app would have a
chance to work, even though it performs calls that MS said not to do.

I have started a patch to use SendMessageW instead, then realized that I'm not
yet familiar enough with MS-Windows' messaging.

Please report back ASAP, as I could give you yet another patch to try out that
would call midiStreamStop and Restart using PostThreadMessage only, without
waiting for SetEvent.
