"it didnt show up in search.."
Actually is still doesnt...
If you try to search for xOx Heart blank manufacturer and blank function etc.. then no hits...
Its doesnt show up if you just select Grayscale.
Open Music Labs, the ACTUALLY designers dont even show up in the manufacturers, grayscale only make the panel...
So... Now I have one in my Rack at least.. by pressing + on the page YOU quoted...
but no one else can find it!!!

... or... im doing sommat wrong...
