Yes, you need to be mindful of matching sample rates when using the BIAB VSTi plugin in your DAW app. If I decide I want to do this next project @ 96K, I need to be sure that the Windows Audio app is at 96K as well or the BIAB VSTi plugin with not work correctly. Conversely, some multi-media apps and online content (that rely on the Windows Media Player) can sometimes change the sample rate, so the next time you use your DAW app the BIAB VSTi plugin will not work until you go back in and manually change the sample rate back to match your DAW project. PGM should further explain this in detail, in it's BIAB VSTi plugin documentation & video. This will help ensure a positive customer experience using the plugin.
Now that it works as advertised, I must say I really like this BIAB VSTi plugin as it was the main reason I did the BIAB 2019 upgrade in the first place. smile
