Hi, found a way to get DirectMusic with a WDM/KS midi driver going in W2K, turned out that the sample source code isn't complete. Now if I could find an application that supports it correctly??? Cubase/Nuendo sometimes use timestamps in the past, so how is this supposed to work sample accurately? Is something in the DirectMusic filter chain fiddling with the timestamps?
