I’ve just noticed something: HSO seems to have disappeared from the Steinberg website! I can’t see it under the “Shop” or “Products” tabs.
However, if you click on the big “VST” button below the top picture on the Home-page, you get a nice picture of all the products, including HSO, but in the text below, it’s ommited.
Is HSO in the process of being updated? New Sonic interface maybe?? Full integration inside H4 maybe???
