at the moment this feature is half complete.
Try this on your Faderport and Studio One
On the Faderport press the Shift key and F4, this combo opens the Browser. Now press the F4 key again to deactivate it. All F keys should now not be lit.
With the Effects section of the Studio One Browser now open use the Faderport's big blue scroll wheel to move up and down your plugin list. Use the Faderport's left and right arrow keys to open and shut a plugin manufacturers folder to expose their plugins.
Here is where the Faderport now needs to be updated, as pressing the big blue scroll wheel does not select and insert the plugin on your track, instead it does nothing. Please Presonus make this happen as i still need to reach for the mouse
