hi experts,

I am developing Win XP/2000 s/w for a usb device that
generates midi messages. We have vender supplied USB
drivers (.sys and .dll). Using the dll I am able read the
midi msgs from the device.

But I need to forward these msgs to applications like
CakeWalk, ProTools etc. These apps read midi ports.

So I need to virtual midi port and write my midi msgs to
the port, which can then be read by the apps.

My question is do I need to write a WDM driver for such
simple purpose! If, yes would a simple user mode dll
suffice?

Any help is appreciated ,

thank you - audrey.
