I am having problems calling the function
IDirectMusicPerformance8::ReferenceToMusicTime(...) on a properly initialized
performance interface. The music time returned is zero. Here is the code:
// Assume that pPerf is the pointer to the IDirectMusicPerformance8
interface
pPerf->ReferenceToMusicTime(rt, &startTime);
I have verified that rt is valid when the above function is called.
Somewhere before calling this function, I am setting the performance's master
tempo via the following call
// Assume that ratio contains proper ratio for the desired tempo
pPerf->SetGlobalParam(GUID_PerfMasterTempo, (void *) &ratio,
sizeof(float))))
What could be wrong here? Does the performance object need to be initialized in
any other way (other than InitAudio) before calling ReferenceToMusicTime(...)?
Thank you
Abhijit
