How to separate MIDI events in a Callback

0 votes

Hello. I develop a small arcade game for experimental purposes. This game has a dynamic MIDI music background and MIDI sound effects. To analyze the results of the experiment I need to record all player actions and game events including the sound.
As the music is dynamic, I use a Callback on the music background to record all the music MIDI events but I discovered that the MIDI sound effects also trigger the callback (that I only put on the music play event). The music uses a music-box sound and sound effects are drum sounds. To replay them with the right instrument, I need to separate them.

I tried two different approaches :
- the channel : I tried to identifies the channel used for each instrument but it can vary from one execution of the game to another
- the associated gameObject : if I try to Post the sound effect events with another gameObject source, no sound is emitted... the log show that the events are received by Wwise but not played :

    Same gameObject (SoundControler):

I don't know why no sound is played, I suppose that's because sound effects are synchronized on the music with a stinger and the music is now attached to another gameObject.

I have no clue how to separate the sound FX from music to record them separately (other than removing the stingers). Maybe there is an information in the AkMIDIEventCallbackInfo structure that can allow me to separate music and sound FX but reading the documentation I do not find anything useful.

Do you have any clue how to achieve this ?
Thank you in advance for any help you could provide.
