Hi, I modified the 'sb16' example from the Win XP DDK such that it loads and a sound device shows up which is selectable for sound playback in the sound setup in the device manager. Now I want to add Midi (DMUS) support. To do this I took the 'dmusuart' example from the DDK and modified the 'sb16' adapter driver such that it calls this DMUSMiniPort init instead of the build-in miniport and create a DMUS port/miniport combination. This appears to go well (no errors reported by XP). I can hower not see nor select this MIDI port in the sound setup in the device manager or in a sequencer program like Cubase. The .inf file I created with 'geninf' and after that I added the directives needed for miniport instalation as descibed in the DDK (and I looked in the 'sb16' inf file as example). My question is: How is the midi 'recognized' by XP? Is there a pointer/link where I can find information on this issue? Is this a registry issue or is the 'dmusuart' example from the DDK exposing the wrong pins?
