   DirectMusic & C#
  The only way to work with DirecMusic in c# is with DX7 & interop?Any C# wrapper for DX9?Can somebody tell me why MS doesn''t include DirectMusic with the DX SDK for C#? 
  They simply have not created managed extensions for all of the interfaces yet.  You will notice DirectMusic, DirectShow and DirectSetup are missing.  There is a simple wrapper called Microsoft.DirectX.AudioVideoPlayback that provides rudimentary playback capabilities.  If you need more functionality, you will have to look into the interop method. ; I need to work with midi messages.I have tried to work with toub but i think that DX is better ;  I have playing my class with interop but when i want to implement the callback (CreateEvent) i got a parameter error "parameter in not correct"All DX7 methods works with InterOp?------------public class MyClass : DX7.DirectXEvent{..int hEvent = directX.CreateEvent( this );// orint hEvent = directX.CreateEvent( (DX7.DirectXEvent)this );..}// cause error
