XYZControl
[edit- just realised i'd not explained what it is for incase it's not obvious!]:
This plugin goes before any synths/fx that have midilearn or general CC control features. You have 3 assigned control axes (vertical, horizontal, and 'size' via the mousewheel), all of which can be controlled at the same time using your mouse. Stick Tracktion into automation-record mode and it will store your movements on the track (editable with T's automation line controls). You can resize the window to any size you like, so you can make it fill the screen if you want to

XYZControl
remember, you can use the wheel whilst you're dragging, so that's three dimensions of control in one go
also, to help when using midi learn, you can right-click the CC number selectors to send a single message out on that number (to save you from having to carefully move the ball in only one direction).
hope it's useful!
