I can’t answer point 1.
But for point 2, program a button for the Jog wheel with the Right and Left ARROW keys. This will not only scroll tracks, but scroll anywhere where you would use arrow keys, for example in the open Plugin list.
You can follow these instructions:
You create a soft key assignment so then when it is pushed, the Artist Control Jog wheel will take on the function you assign to it, until it is pushed again.
You go to Eucontrol and go to the “softkey” tab, there you will find a drop down window with the different devices that you can program.
Select TU Wheel, (I know you don’t own it, but that does not matter)
Double click the “Jog” button.
A window pops up, at the top select “Add” ,a window pops up to name your new custom command.
After you name it, you are left with a screen that has the drop down menu for “Turn Jog Right” and “Turn Jog Left”
So what you need to do in Cubase is, assign a keyboard keycommand to what you want the jog wheel to do when you turn right and left, this can be anything, in your case Right and Left Arrow keys.
Now on this screen under Command drop down menu, select “Key” and enter the Cubase Keycommand you want to trigger.
Do the same for the “Turn Jog Left”.
now close that window
Back on the “softkeys” tab select “surface” or “touchscreen” depending on where you want to put the button to “activate” the special jog function.
after selecting a location
Select the “command” to program to that softkey
THIS IS THE IMPORTANT PART in the command drop down menu, your going to select “wheel”
then in the Wheel drop down menu on the right select the icon that look like an MC Control
and select “Jog”
under that in the “function” drop down menu, Select you custom jog function you named.
now when you hit that softkey, the jog wheel will take on that function that you programmed until you hit that softkey again to turn it off.
You can put ANY key command on the Jog wheel this way.
