@Ikarus_CT, you are making the assumption that Touch:PC has a "Zone" built-in. They might have done that, but I don't see any reason to believe they did.

It sounds like Touch:PC is just the GUI you see on the C15 in a fixed 1920x1080 window.

Running core + storage on QNAP + Touch:PC on your Windows machine means you still need an Meridian audio endpoint, unless you are planning to use Control:PC/Control:Mac as your endpoints. As far as I know, that's the only software endpoint Meridian releases.
