The JOYSTICK horizontal (X) and vertical (Y) values can be used as modulation sources in the PARAMS page. Pressing the gray button next to the JOYSTICK changes between ABS and REL modes. ABS (Absolute Mode) follows (and transmits the values as modulation sources from) the JOYSTICK movement on a 1:1 ratio. When you release the JOYSTICK the values snap back to their center values. In REL (Relative Mode), the JOYSTICK ‘accumulates’ values in the direction of the JOYSTICK, but will not reset them to the center values when you release the JOYSTICK.
In ABS mode, you can press and hold the red MOTION button and it will sample the XY movements from the JOYSTICK as you move it then continiously loop the captured values. To clear the motion buffer, quickly tap the red MOTION button once and it will create a buffer of zero length, thus stopping any modulation.
You can determine the mode the JOYSTICK is in from the display MODULATORS page, accessed by pressing the DISPLAY button until that page is shown.
In this example the JOYSTICK is in REL (Relative Mode).
