Update:
Okay, I finally got it working in Studio One 3 but not by the right click method. Studio One 3 has a feature called "Control Link" which I had to use as a "bridge" to learn the knobs and faders of Dune 2. So it had nothing to do with Dune 2
or the Alesis controller.
The plugin host window in studio one 3 shows this in the upper left corner,
but only after you click on the gear icon in the upper right corner (see screenshot 09). This highlights your controller name in yellow and exposes the otherwise hidden control link area on the left (see screenshot 10). If you move a control in Dune 2, the name of the control appears in the control link area. If I move a control on my keyboard the name of the control appears on the right in the same area. Here's the tricky part: The arrow icon (a white triangle) between the two of them has to be clicked on, which highlights it yellow (see screenshot 11). THEN the controller will work. This procedure points the hardware control to the Dune 2 control.
Also FYI, after testing other plugins, the only ones that worked with the right click method were studio one's native plugins. All the 3rd party plugins I tried had to use the hidden control link method that I have explained here. I know this is a somewhat confusing procedure, until you do it once or twice, but I must say I really love Studio One 3 Pro, so I can deal with the slight inconvenience but the right click method would be more convenient. And now I also really love my new Dune 2!!
