Guitar for keyboardists?

We know many keyboardists that struggle with the concept of playing guitar. It can feel very unnatural strumming/twisting your hand into shapes after coming from a nicely spaced-out piano keyboard. Thankfully, Marcodi instruments (www.marcodi.com) came up with the Harpejji – a table top/stand-mountable guitar-based tapping instrument that can be strummed or tapped, with a note layout based on the piano keyboard. Stevie Wonder now endorses it too.
