He used the natural samples of my Baby Piano free sample set. This means that the Baby Piano VST corresponds to the "Real white keys" program of the free set, the real acoustic Baby Piano mapped from G3 to F5 only on white keys. The pitch heard does not match the key pressed except for G3 and it has velocity layers.
Note that it's not up on the website yet but it can be downloaded here:

Please refer to the included documentation for more info.
As it is the first time I released a product made with Maize Sampler, please report any problem you may have and also let us know if it works correctly on your system.
