Physical versions of spongefile's popular cheat sheets: vinyl keypad overlays and system-shortcut stickers that sit on the device itself, for the EP-133 K.O. II, the EP-1320 Medieval, the EP-40 Riddim and the PO-33 K.O!. They're printed locally in Finland in small runs, with an application guide on the shop. Sign up there when a run is sold out.
