Heavy sound/input lag in piano games

[poke_haven]

For a couple days now, the sound and input is very laggy/delayed. My piano system using timeposition and now it is feeling while setting it, slower.

You can test it out here, WIP - Roblox

ROBLOX team fixed this issue previously in another thread by rolling back a change that inadvertently made setting TimePosition slower, looks like we need it again. Sound TimePosition inaccuracies

Expected behavior

My offset function used to work perfectly, until recently a couple days ago?

What was once synchronized audio playing, is now delayed for some notes.

Can you try using PlaybackRegion instead and see if the problem is identical?

It’s cause of a flag, a roblox staff member fixed it last time with that.

Hi, would you be able to put together a repro file that we can look at? It doesn’t have to be the full piano system, as long as it shows the way you’re dealing with playing multiple sounds at the same time.

I have sent you a message with the file contained. Just press 3-4 keys at a time.

Thanks for the info - we tracked down the issue to a different cause and made a flag change to address it. Can you check if it’s still happening to you now?

It appears to be functioning back to normal again, thank you very much!
