Problem:
Cubas SX V1.0 hangs 15 seconds on the MIDI initialisation
if our AV Stream driver exports a MIDI Pin for rendering.
Detail:
The process services.exe uses 100% CPU time during
initialisation. The Midi Pin works well with other
applications and it works also with Cubase.
OS: Windows XP, SP1
DirectX: 8.1
PIN Properties:
MajorFormat = KSDATAFORMAT_TYPE_MUSIC;
SubFormat = STATIC_KSDATAFORMAT_SUBTYPE_MIDI;
Specifier = KSDATAFORMAT_SPECIFIER_NONE;
Technology = KSMUSIC_TECHNOLOGY_PORT;
The pin does not implement DMUSIC or any other properties.
Is it required or recommented to implement additional
formats or properties?
I'm not sure if this is caused by Cubase, Windows or our
driver. Can you give me a hint to solve this?
