Does Link mode work in other DAW's the same way it does in Studio One. The encoder top left takes over any parameter the mouse hovers over in Studio One. Such as channel faders. Or gain adjustments. It's is also stepped and can make fine adjustments. You don't have to click on the parameter either. It is a nice way to adjust plugin parameters too. The larger encoder on the right can control master volume when that mode is engaged.
There is a mode where the fader flips to controlling pan and the encoder controls volume. These may be the deeper Studio Integration features. It is made for Studio One trust me on that. It is super powerful working in Studio One mode. I have the new Faderport 2018 single fader version and Faderport 8 working together. In this mode they are powerful together.
Future firmware updates will ensure it gets new features added to its already extensive feature set.
ATOM is coming and it is going to be amazing controlling not only Impact XT but a lot of Studio One at the same time. ATOM will have all the other operating modes similar to Faderport series.
