I haven’t tried it with a Windows touchscreen, but we do that on iPads all the time. There are certainly people using touchscreens with Mixing Station. Be aware that there are very tight limits on how many remote devices an SQ can support. You can run 3 instances of Mixpad, or 2 instances of Mixing Station. If you’re cabling to the laptop with ethernet, you can run an audio feed from the board down the unused pairs in the ethernet cable and listen to what’s soloed up. You’re liable to conflict with the house tech, of course, since the desk will also be soloed.
