Select a node on the grid with the D-pad and the X button,
and that sound will be played in time. Press O to stop/
resume playing, and use /\ (triangle) to clear the grid.
Press START to use the menu, and use the D-pad to select a
menu item or change a value (like the tempo), and X (cross)
to confirm your choice. Press SELECT for help.
