As you might know, Windows 8.1 is about to be released. Currently, we are testing all Steinberg products for Windows 8.1 compatibility. The testing is still going on, so we can’t provide you with the final results.
However, what is known so far is that some Steinberg hardware products need to be updated to ensure full compatibility with Windows 8.1. Our development team is already working on driver updates for the affected hardware products in order to make them available as soon as possible. Currently, we recommend you not to upgrade to Windows 8.1 yet and wait for the final testing results.
We will keep you up to date.
