Quote from: "LiquiChime73"A panel of rubbery, textured drawer and/or cupboard liner might give you a sufficiently-grippy surface. I've got a Mark I with a rounded. top. I bought a roll of black liner at a dollar store and cut a piece as long as my synth is wide. It works.
That's what I use too, I've got my whole home studio on top of my Rhodes and everything just sticks to it.
