I've seen this MPE compatible midi controller before but I didn't pay attention to it as other MPE controllers such as the Eigenharp and the Grand Stick looked more interesting. It has been around a few years. Now that I've seen a few Linnstrument video demos, it is quite interesting.

I would say that certainly Linnstrument can add finer expression and realism to hardware both keyboard and module, but for now it seems that software sounds are much more ready for MPE.

A nice demo
