I have 3 questions about how midi devices (legacy and WDM) are related to the 
registry Key 'HKLM/Software/Microsoft/Windows NT/CurrentVersion/Drivers32':

I've noticed that midi devices seem to have problems on win2K and winXP when 
the 'midi' index gets past '9':
   midi = MidiDevice0
   midi1 = MidiDevice1
   midi2 = MidiDevice2
   midi9 = MidiDevice9
   midi10 = MidiDevice10 // windows does not seem to recognize this device
First Question: Is there a cure for this?  Maybe a different index than '10'.

Also, there is often a number of 'redundant' items. For example, in winXP if 
there are multiple wdmaud.drv MidiDevices, can they all be combined to a single 
midi index?
   midi2 = wdmaud.drv
   midi3 = wdmaud.drv
   midi7 = wdmaud.drv
be replaced by
   midi2 = wdmaud.drv

In win2K are empty indexes useful or can they be removed without causing 
   midi2 = MidiDevice2
   midi3 =
   midi4 =
be replaced by 
   midi2 = MidiDevice2
