volume controller should probably be 127, not 100. Actually, there's some
confusion as to whether this message should touch the volume controller at all.
Added some comments to hopefully clarify that a bit.

Controllers Off" messages. This should, among other things, reset the channel
volume to 100. Until now, however, we did not re-adjust the volume by the
master volume (like we do for ordinary volume control changes), so all of a
sudden there would be channels playing at the wrong volume.
This was particularly noticeable if you first turned down the music volume to
really low.
