Log:
Renamed legacy mpu401 driver to mpu401_nt4 and disabled the building of 
all drivers in this directory (all are incomplete, none of them work and 
are superceded by the Kernel Streaming alternatives.) Leaving drivers in 
source tree for reference at present but they can eventually be removed.

-REACTOS MPU-401 MIDI DEVICE DRIVER
-by Andrew Greenwood
-----------------------------------
-
-This driver initializes the MPU-401 MIDI/joystick port found on
-most sound cards, and allows the sending of simple messages.
-
-It's far from complete, and at present will only support 1 device.
-
-In Bochs, the MIDI output will be played using whatever device is
-set up in Windows as your MIDI output.
-
-For real hardware, the output will be played to whatever device is
-attached to your MIDI/joystick port, or, in some cases, the wave-table
-or other synth on-board your card (note: this is NOT an FM synth
-driver!)
-
-
-Thanks to Vizzini and all the other great ReactOS developers for
-helping me code this driver and also for giving me encouragement.
-
-I'd also like to thank Jeff Glatt, whose MIDI and MPU-401
-documentation has been a valuable resource to me over the past few
-years, and who provided me with almost all of my knowledge of MIDI
-and MPU-401. His site is at: www.borg.com/~jglatt/

+REACTOS MPU-401 MIDI DEVICE DRIVER
+by Andrew Greenwood
+----------------------------------
+
+This driver initializes the MPU-401 MIDI/joystick port found on
+most sound cards, and allows the sending of simple messages.
+
+It's far from complete, and at present will only support 1 device.
+
+In Bochs, the MIDI output will be played using whatever device is
+set up in Windows as your MIDI output.
+
+For real hardware, the output will be played to whatever device is
+attached to your MIDI/joystick port, or, in some cases, the wave-table
+or other synth on-board your card (note: this is NOT an FM synth
+driver!)
+
+
+Thanks to Vizzini and all the other great ReactOS developers for
+helping me code this driver and also for giving me encouragement.
+
+I'd also like to thank Jeff Glatt, whose MIDI and MPU-401
+documentation has been a valuable resource to me over the past few
+years, and who provided me with almost all of my knowledge of MIDI
+and MPU-401. His site is at: www.borg.com/~jglatt/
