Wwise SDK

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.
