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: https://youtu.be/9-gZ9TgMee4
The Digital Grand shows the position of the pedal in a bar on the right side.
