Can anyone direct me to something that would fix this, just started this morning... my recorded vox track "plays" late, about a half=second behind how I recorded it. I've tried restarting RB, also restarting my system, no change. Same happens if I record a midi track (like hitting notes on the beats)--I can see on my piano roll that they got recorded later than I played.

Thanks for any diagnostic help!

It is very hard to help when we don't know your system so including your OS, RAM, audio interface, etc would be a big help.

But the first thing the I would do is to check your audio interface drivers and buffers. I have had both Win 10 and BiaB updates change those settings. If you have an external audio interface also check your device manager to see if Windows has activated your motherboard sound chip, usually a Realtek chip. If so deactivate. Then check RB for the correct audio in and out settings.

Good luck.

As Mario said, this sounds like RB may not be using your ASIO drivers.
Check Prefs-Audio-Drivers section.
