One of the most effective settings in KONTAKT / KONTAKT Player: have a look at KONTAKT’s OPTIONS-Panel -> Engine-Tab -> CPU overload protection. Set it to relaxed if it was set to disabled before:

We actually do not limit the number of maximum voices in the C. Bechstein Digital Grand by default. It´s set to 500 in the version 1.0 NKI´s.

Please adjust the maximum numbers of voices to, let´s say, 150-200 to avoid a too high CPU usage. 

(Side note: in many other libraries, this number is either set down to a less lower value, or the number of voices will be trimmed by a Script in the background – we try to keep this functionality of KONTAKT as transparent as possible for the user).

Yes, the Digital Grand supports Half-Pedaling with corresponding Controller-Pedals. BTW, you can see this in our Overview-Video:
