When I play midis with DirectMusic (segments to audiopath to performance), they play at a crazy fast tempo... insane ! But unlike my graphics engine, I don''t need speed like this. I would like my midi to be playing their original speed... how ?

I do not have this problem.

What is the code you are using? as by default Direct Music plays according to the "written" tempo.

I am wondering if it is :

m_pPerformance->PlaySegmentEx( m_lstMidis[_indSound], NULL, NULL, DMUS_SEGF_DEFAULT | DMUS_SEGF_SECONDARY, 0, NULL, NULL, NULL );

that cause the problem. I don''t know if by using the DMUS_SEGF_DEFAULT and DMUS_SEGF_SECONDARY flags, I am soing something wrong...

I''ve found it !
The problem was has I suspected. It was the DMUS_SEGF_SECONDARY flag that caused all this speed deformation. Thank you RhoneRanger for your post.
