This thread is a bit old, but has anyone figured out a solution to the black screen bug?
I just got Scaler 2. Running Ver 2.1.2 on Studio One 4 windows.
I sometimes get Scaler to work the first time I open the plugin, but after that I keep getting the black screen. While trouble shooting, I discovered it I have Scaler 2 in open on a track and I disable it then enable it, I can get it to work again; however once I close scaler I get the black screen again.
