Thanks @dan.reynolds ! And that makes a ton of sense. I’m digging a bit more and I am getting closer and closer but am still fighting just getting the time synth component to make sound happen in the editor similar to audio actors having that preview button. I’ve been hacking away at a few things and I have confirmed that the audio thread is working now in-game (I got it in the editor too by hacking away at LaunchEngineLoop.cpp line 2164… but I imagine with things like the sound cue editor this will be a crash-fest long term given the information you just provided me with. The event quantizer is also still outputting 0 playback but that is because its reliant on OnGenerateAudio to be running to update NotifyEvents to get proper playback time from frametime. Can you think of another instance that is blocking the synth components audio in-editor? Seems to be something being blocked somewhere in there just slowly been hacking away through the code to find it. 
… I am determined to break things for sure and appreciate any help in doing so XD. I feel like I am actually making strides though today vs yesterday so thats… better.
Once again your time is appreciated!
