Wow - I cannot believe that someone who is "specialized in Microsoft's audio
and video technologies" (taken
from the about on his blog) initially does not know that a USB MIDI-class
exists and then does not know
that a driver supporting this is being shipped since Windows 2000...
Apart from that - a proposal:
Have you guys ever thought about implementing the MIDI-subsystem like TAPI?
Where you have the framework
expose the existing standardized APIs (DirectSound, legacy MME, possibyl
WDM-KS) and provide the actual
MIDI-backends via a "Midi-Service-Provider" (like TSP, TAPI Service Provider).
This way some Microsoft component (like usbmidi.sys) can provide the basic
backend-support (and manufacturer-
specific-drivers/providers can use their own proprietary implementations on
their favorite transport-media).
The MIDI-framework will expose all those registered MSPs as MIDI-devices
(either DirectSound, legacy MME...)
and provide higher level abstraction (like multi-instance abilities where the
framework would be doing
the required midi-merging for example, or stuff like surprise-unplug recovery)
This way anyone out there could create their own "virtual MIDI ports" on the
fly like I have done with
my virtual MIDI-driver
(http://www.tobias-erichsen.de/software/virtualmidi.html) without the need to
acquire very specific "voodoo-knowledge" about driver-writing and the WDM-KS
subsystem...
If such a framework is to be devised right now, HD-MIDI should be taken into
the picture. So this framework
should be able to expose the Standard-MIDI APIs, but also a new standardized
one for HD-MIDI.
An MSP (MIDI Service Provider) in this framework could provider backends for
either SD-MIDI, HD-MIDI or both.
This would move Microsoft even in a position that is more advanced than what
Apple & Linux currently provide.
