User-mode midi-driver

Hi everyone,

I'm not sure if this is the right place to ask for, but I will just go
ahead:

I'm currently writing a virtual midi-driver which is implemented in a
user-mode-driver mymidi.drv. I have taken the sample from the
nt 4.0 ddk and adapted it to my needs. I got two problems:

1.) If I install on a system where no midi-driver has been installed
previously, my driver will not show up in the audio & midi settings
in the control-panel. I think that I need to install some MS component
which will not exist until the first midi-driver is installed...

Any hints, on what I need to include in my inf-file?

2.) If I get this thing installed right (on a system which already got
a midi-port active), the driver is installed. Unfortunately there,
the audio & midi settings control panel applet won't start any
more. With OutputDebugString I found out, that my driver is
loaded and the DriverProc is called with "DRV_LOAD" - but
that's it...

Does anyone have ideas why driver-loading seems to fail (even so bad
that the control panel applets aborts)?

Best regards,
Tobias

Are you sure your hardware supports midi play back.

You might look at the source code of your sound card driver and see if
the midi object code is present. If you look at the Windows Sound
Driver Source "sndsys" you will see that midi support is commented
out.

Like I wrote in the original post, the computer I use, does not have
any MIDI-hardware. My driver is a pure virtual driver, sending
and receiving the MIDI-stuff over the network.

Hi everyone,
