The XY Controller makes for more tweaking fun. It's a classic, and we didn't dare to leave it out! It can control two parameters with one mouse movement. When browsing presets don't forget to listen to the sound mangling possibilities provided by these controllers.
To add an XY controller as a modulation source, click the + button in the source selection bar and click New XY Controller.
Because the XY controller has two "outputs", it also has two source drag buttons labeled X and Y. The slots for the XY controller are grouped in two rows, with the X-slots at the top. For example, in the screen shot above, the X axis controls the output panning, while the Y axis controls the level.
The Remove button deletes the XY Controller.
With MIDI learn, you can set up a hardware MIDI controller to control the XY controller. So if your MIDI controller has XY-functionality you can directly control Twin 2.
