Touch or move your finger on the gridded part of the screen. A marker will follow your finger to indicate the current
position. The X axis is the horizontal axis, increasing in value as you move right. The Y axis is the vertical axis,
increasing in value as you move up. Each axis is labeled with its assigned parameter.
When an effect has a beat division parameter, the current division will be highlighted as an entire column.
Effects are differently colored for easy visual distinction: beat-synchronized effects are blue, while manually
controlled effects are green.
XY Mode with a beat-synchronized effect.
While touching the XY pad, tap Latch in the lower-left corner to keep the marker on the XY pad even after you
release it. The marker will remain there until you touch another part of the XY pad or until you tap Latch again.
Use the Setup button to show or hide the Setup panel, which controls how the XY pad behaves.
Use the Preset field to select the effect you want to use in XYFX Mode.
