Yes, I use VMware Workstation which emulates a Sound Blaster PCI 128 
sound card: depending on the place the driver is either called 'Creative 
AudioPCI (ES1371,ES1373)' or 'Creative Sound Blaster PCI'.

Strangely enough, my Win9x VMs use the same driver (but only older and 
for win9x obviously) and although they all have a Midi device, none of 
them seems to get stuck in the midi test. Only the Windows XP and NT4 
VMs seem to have trouble.

I tried commenting out all the UART lines in wdma_ens.inf in Windows XP 
as described in but 
this had no effect. I also tried reinstalling the device afterwards (by 
deleting it in the device manager and letting XP redetect it), but to no 

The driver's Properties tab in the hardware device manager gave me some 
hope because it has a 'Do not use MIDI features on this device' radio 
button. However checking it disables the driver entirely :-(

So unless someone else finds a solution maybe the route to go is to 
apply this patch:
