Apparently they are using something called “Physical Behavior Modeling” to simulate the bellows action of a real accordion. You can also get all the standard keyboard sounds as well as, you know, pretty much anything else you want, since the Roland has a MIDI out. And of course, the FR-7 comes with built-in speakers, so you and your robot monkey can work moon base street corners from dawn ’til dark side.

That reminds me of a musician joke. If you throw an accordion, a tuba and a banjo from the top of a 30 story building – which instrument would land on the street first?
Answer: Who cares!
