which would mean that none of the Kronos/Krome grand pianos are implemented in the same quality without loops. However, as I found out, the better M3 piano with its 128 MB sounded very similar.
But obviously Korg doesn't try to come close to Kronos dimensions here; it is also inferior to the Yamaha MoXF specs with its 700+ MB preset sounds plus up to 2 GB flash user samples.
