In fact, the global playLoudness does affect the system volume -- I've built
stacks that use the playLoudness to fade out the playback of looping sounds.
I think you're running into something else.  I believe on Windows, MIDI has
a separate volume from the system volume so while your script can affect the
volume level of all *sounds*, it is not changing the *MIDI* volume level.

I would look on the net to see if there's any MCI control string for the
MIDI volume level.  A quick search came up with these references that
appears to indicate volume control is *possible*, along the lines of "set
MIDI Volume To...":

Here are Visual Basic files, one of which claims to allow MIDI volume
