XACT: Pitch event not supported

[BMarques]

On my piece of code, I have
soundBank = new SoundBank(engine, contentPath + "Sound Bank.xsb");

Apparently this is causing a "System.NotImplementedException: 'Pitch event'"

Is there any known technical reason for this to be like this or can I try to fix it and submit a PR?

Thanks.

The handling of pitch events needs to be implemented in XactClip. I've never worked on the XACT stuff, so I don't know how it works exactly.

I also don't know if the format is documented somewhere, cc @tomspilman.

@Jjagg - It will take a little investigation to work out. The pitch event works similar to volume. What i do when i work these out is look at the settings in the XACT tool... set everything to some unique values... then try to work out the decoding.

All this data is encoded in the pitch event. Usually they stick to similar formats to other cases... so i don't expect this to be too tricky to figure out. Also from my experience the "repeats" case is usually a separate pitch event id (like the volume repeat event).

We have a Tests.xap file in the unit tests along with some tests in:

https://github.com/MonoGame/MonoGame/blob/develop/Tests/Framework/Audio/XactTest.cs

We've used it to do some basic XACT tests and be sure different formats are parsed. Adding a sound cue with a pitch event and making it load would be the first step.
