Why is there a delay before hearing sound from the Note On node from the Modular Synth Component using a Quest 2?

Hello! I found that there is about a half-second delay after the Note On node is called before hearing any sound from the Modular Synth Component while using the Quest 2 on stand-alone. I tested this with a blank project, and still found the issue to persist. This issue pretty much completely ruins real-time music synthesis based on user input with the Quest 2. It’s very easy to replicate, just add a Modular Synth component, use the Start node at Begin Play, add the Note On node to a button input with the Quest controller, and build the project to run on standalone. I’m unable to carry my project forward if this issue persists.

Just chiming in that even on a desktop PC / Windows / Mac environment, the lowest latency time I can get from UE5 is about 150ms; way outside the range of a real-time music game. I’ve tried setting the buffer size / number of buffers down, but nothing works.

I’m also at a standstill here – I want to make a rhythm game but this lag is unbelievable.
