That’s not the end of the story, either; the update knocked out my Korg MicroArranger Air. Found out on the net that many others are having the same issue and that Korg is working on a new driver now. I hate to mess with registration files, but I did and in the end I got the keyboard back. Build 1903 is a major update, and it “shocked” my machines and applications in them!!! It took my machines a long time and several boot-ups. I think this is really the first time a Windows update gave me issues across the board. Other than that, Windows is not really a bad environment to run DAWs and VST plugins. Of course, a fine app like Gig Performer makes it much easier.
