Spontaneous Christmas Carol Singing with the Roll-up Soft Keyboard

Last week I was invited to a SantaCon Christmas party where EVERYTHING was into place (foooood!), except that they had Lady Gaga blasting over the speakers. Good thing I brought my roll up keys, so we ended up caroling. I bought these keys online, but I`m looking for more roll up keys like these, maybe some other brands. Anyone has any suggestions?

At least with this kind of piano you don’t have to worry about slight differences in key depth affecting your technique…

"o.O. I always dreamed of a piano o carry around, like in Startrek…Would be great if these would feature hammer mechanics and dynamic playing.

That looks pretty cool
