It is actually hard to pass out the right number of stars for this one as the sound is not an ordinary piano, neither is the interface. The piano tries to convey the atmosphere of the abandoned city of Pripyat, the center of the melt down disaster in Tjernobyl april1986. The result is both sounds and a visual interface (pictures) that is kind of "suspense" like. My thought goes to scores for horror movies. And what a horror the disaster itself must have been. So in that respect it is a full 5 star. The interface comes with a bunch of pictures from Pripyat and also convolution IR's that is recorded on different places in the city. The different IR sites is given as both presets and as a convolution menu to choose from. I was however kind of surprised that there was almost no difference between the presets. At first I thought it was something wrong with my installation, but I found a review on YouTube that took me through most presets and they sounded just like my installation. So no matter if the IR is in a huge hall or a small room, they sound much alike. In that respect it is not a 5 star. Also the installation procedure is a little querky and not up to todays standards, so that would also call for a lesser number of stars. However I have bought this for the sound and even if it is not for everybody, it fits right into my projects, and the sound is what it is all about, right?
