◆ PostMIDIOnEvent()

AKSOUNDENGINE_API AkPlayingID AK::SoundEngine::PostMIDIOnEvent	(	AkUniqueID	in_eventID,
		AkGameObjectID	in_gameObjectID,
		AkMIDIPost *	in_pPosts,
		AkUInt16	in_uNumPosts,
		bool	in_bAbsoluteOffsets = `false`,
		AkUInt32	in_uFlags = `0`,
		AkCallbackFunc	in_pfnCallback = `NULL`,
		void *	in_pCookie = `NULL`,
		AkPlayingID	in_playingID = `AK_INVALID_PLAYING_ID`
	)

Executes a number of MIDI Events on all nodes that are referenced in the specified Event in an Action of type Play. The time at which a MIDI Event is posted is determined by in_bAbsoluteOffsets. If false, each MIDI event will be posted in AkMIDIPost::uOffset samples from the start of the current frame. If true, each MIDI event will be posted at the absolute time AkMIDIPost::uOffset samples. To obtain the current absolute time, see AK::SoundEngine::GetSampleTick. The duration of a sample can be determined from the sound engine's audio settings, via a call to AK::SoundEngine::GetAudioSettings. If a playing ID is specified then that playing ID must be active. Otherwise a new playing ID will be assigned.

Returns: The playing ID of the event launched, or AK_INVALID_PLAYING_ID if posting the event failed and an error will be displayed in the debug console and the Wwise Profiler.
