Hi all,
Could you please tell me if this pseudocode is the right way to do it? I
don't know nothing about COM programming and if it's the good way to
instantiate a track object....
////////////////////////////////////////////////////////////////////
Tempo : TDMus_Tempo_Param;
DMTempoTrack : IDirectMusicTrack8 = NULL;
CoCreateInstance(CLSID_DirectMusicTempoTrack, nil, CLSCTX_INPROC,
IID_IDirectMusicTrack8, DMTempoTrack);
DMSegment2.InsertTrack(DMTempoTrack, $1);
Tempo.dblTempo := 130;
DMSegment2.SetParam(GUID_TempoParam, $1, DMUS_SEG_ALLTRACKS , 0,
@Tempo);
////////////////////////////////////////////////////////////////////////
No compilation error, just no sound anymore. If I deleted the Setparam
call, everything is fine.
Thanks
