This is how I do it for a four port virtual midi driver:
// Start the UART miniport.
//
ntStatus = InstallSubdevice(
pDeviceObject,
pIrp,
L"VMpuA",
CLSID_PortMidi,
CLSID_MiniportDriverUart,
NULL,
ResourceList,
IID_IPortMidi,
NULL,
NULL
);
ntStatus = InstallSubdevice(
pDeviceObject,
pIrp,
L"VMpuB",
CLSID_PortMidi,
CLSID_MiniportDriverUart,
NULL,
ResourceList,
IID_IPortMidi,
NULL,
NULL
);
ntStatus = InstallSubdevice(
pDeviceObject,
pIrp,
L"VMpuC",
CLSID_PortMidi,
CLSID_MiniportDriverUart,
NULL,
ResourceList,
IID_IPortMidi,
NULL,
NULL
);
ntStatus = InstallSubdevice(
pDeviceObject,
pIrp,
L"VMpuD",
CLSID_PortMidi,
CLSID_MiniportDriverUart,
NULL,
ResourceList,
IID_IPortMidi,
NULL,
NULL
);

Subject: [wdmaudiodev] Naming multiple MIDI miniports
I have successfully written a small MidiBridge (a kind of virtual Midi
interface driver that allows me to establish a communication path between a
Midi host and my own application). I would like to extend the number of MIDI
ports that are offered by the driver.
What is the easiest way to achieve this?
1. Changing the topology (maybe multiple pins? Do I need additional
Synth-Nodes?)
2. Increasing the number of instantiated miniports?
Besides these alternatives: How do I give distinct names to the offered midi
interfaces? For now, I name it in the FriendlyName-section of my INF-file
Thanks for any help,
Dominik
