I see the grayed out rings on certain parameters of the Phaser algorithm. However the reason I think you have a bug is that in the Phaser algorithm, you cannot get either of the two buttons on the sides of the ribbon strip to illuminate at all. It could be an iPad issue–I'm using an iPad 3–but I tend to think it a bug.
Are YOU able to get either button to stay illuminated in the phaser algorithm? If they don't stay illuminated, you cannot map the Params after all.
