Todo

in(): compile only: statics can't be conditionally initialized. move to be a member!

Init()

::NTSTATUS __stdcall dxd::dmus::miniport< stream_t >::Init ( ::IUnknown * adapter, ::IResourceList * , ::IPortDMus * port, ::IServiceGroup ** service_group )

IMiniportDMus

reference IPortDMus,

create obligatory IServiceGroup and reference it

NewStream()

template<typename stream_t >

::NTSTATUS __stdcall dxd::dmus::miniport< stream_t >::NewStream ( ::IMXF ** stream, ::IUnknown * unknown, ::POOL_TYPE , unsigned long , ::DMUS_STREAM_TYPE stream_type, ::KSDATAFORMAT * format, ::IServiceGroup ** service_group, ::IAllocatorMXF * allocator, ::IMasterClock * master_clock, unsigned long long * schedule_prefetch )

Thats the only place the midiport needs the dummy IServiceGroup member for. The DMUS_STREAM_MIDI_CAPTURE stream will removed again when not providing an IServiceGroup.
