I just got the NAN error in the Natural dynamics . I play with the frequency bands sliders fast (left right) and it gave me the error at the last two sliders (band 8,9). But i think it can give it at other bands too.
The different thing here was that error is not looping. I press CLOSE and ST continue to work. The strange thing is that when i got this error (every time) the sound is affected like boost and reduce the whole level and then again it goes to what it should be.
Ok , start with the default ND frequencies, then make them like in my video, just slide to the next band frequency limit or to the previous band frq limit . You can see what band to what limit is slided in the video.
Then start to play with the band i played.... voila. But make sure you slide it fast and a couple of times ( i don`t know may be needed 5-10 times to get the error).
Check out the video:
