Im using different NI piano VST's: The Maverick, Grandeur, Gentleman. They all have the same problem for me: in the upper register theres a very loud and long release stage after the key is up again. Theres almost no difference between keeping the key pressed and releasing the key quickly, as far as volume and length. I know theres some sound there on a real piano too, and this adds to the realism but imo its way too much. I adjusted the release samples bar in the anatomy section, but this doesnt seem to affect this higher register (or not enough anyway). Its almost as if theres an extra sample that gets triggered here, specifically for this purpose of added realism or whatever. Either way, Id like to get rid of it, or better yet: tweak it.
So then I dove into the editing section of kontakt 6, and I think I found the place to adjust it. I selected the group of a specific key (A#5 i think it was) which if I understand correctly should hold all the samples of that note. Then I went to the amplifier section, and opened the volume modulation AHDSR-envelope. Indeed there is a significant release stage here, so I just turned the release knob down. But then the following happened: I pressed the corresponding key to test it out and the release knob jumps back to its original position. This doesnt happen for any of the other stages (attack, hold etc) which I can happily adjust. Only the release stage does this, which annoyingly is the only thing I want to adjust.
I also tried the same for the 'zone' envelope but the same thing happens. I dont think I fully understand the relation of zone and group yet so I dont know what would be the proper place to do this, but so far both of them just jump back to full release lenght.
Any help would be great!
