Yamano of Japan has come out with a new 61-note MIDI keyboard that is
truly 'portable'.  It is called a 'Piano Roll' keyboard because you
can actually roll it up.  It connects directly to a computer and has
a built-in speaker or you can connect external speakers.  Great for
those temporary MIDI projects!

The Yamano Hand Piano Roll Keyboard sells for 279.00 and weighs 1 kg.
