Note this appears to be more of a design concept vs. an actual product in the works. An upcoming Axel Hartmann?
via Jack Marple's website:
"Jack Marple graduated from Arizona State University in May 2016. He is currently an industrial designer at TEAGUE in the Seattle area."
on the Piino:
"electronic music equipment can be bulky
The goal of PIINO is to create a compact, versatile and intuitive tool for musicians to capture ideas while on the go."
Teenage Engineering's OP-1 immediately comes to mind. Still cool though. New ideas are always interesting.

And via iF World Design Guide:
"Piino is a portable synthesizer that allows electronic musicians to create music on the go. Designers and artist have ways to record thoughts and ideas by sketching it in a sketchbook. Musicians have no such thing. Piino is the solution to this problem; it helps musicians express and compile musical ideas while they are traveling. It is a synthesizer and workstation that includes a 10 key range, customizable effect knobs and sliders, an interactive touch screen, and a trackpad for extra sound manipulation. Piino folds up and becomes a portable device that can go anywhere with you. Piino makes creating music on the go finally possible."
