Just sayin’…
Saw it at NAMM. Neat at first glance. Feels like crap. Sounds like crap. No MIDI.
It’d be kewl if they made one velocity sensitive and with MIDI.
They do it with MIDI in and out now 
I may get one to go in my laptop bag, If i do i will let you know what it’s like.
Nicely spotted, keep us posted mate
Could be nice to embed one of those suckers in a case with a SID or FM …
You know i just realised they do a USB one now too, Its only 37 key though but half the price
haha imagine having a mbsid in a neat case with this folding-out
I saw a kbd very similar to this in Tokyo last week. Called the Roller Piano. They were on clearance for $65 U.S. Link here: http://www.notebook-laptop-batteries.com/Toys-Games/Roller-Piano.htm.
It actually played pretty well, but of course there was no tactile feedback or velocity sensitivity…

It looks like you can get a 49 Key version w/ MIDI for about $70 on eBay. There
are 61 notes versions as well, looks like a couple of different manufacturers are
making these…
