You can not compare them on a video..
The cp not only uses sampling, but also modeling
It has 3 different grands (cfx,c7,imperial) vs one on the Genos
Those piano’s use 28 elememts, the Genos is limited to 8 elements
The keybed is much much more suited for playing piano
In other words, the CP88 piano sounds are a huge step up from the Genos ones..
Comparing them on 2 seperate vodeo’s makes no use
But comparing them in a shop, with headsets on will tell you the true storry..
Its safe however to asume that a typical arranger player will be quite happy with the Genos CFX sound.. it offers everything you need for playing in a busy crowded pup..
However when playing in a concert-hall or as part of a broadwayensemble or even in church it might be another different story..
