Hey everyone, we have seen a few reports of Absynth 6 users experiencing freezing or very long scanning when trying to import Absynth 5 user or third party preset banks. We are investigating the issue but were not able to reproduce it yet. If you are experiencing this, please let us know what your operating system is and if you can, zip the affected banks and either add them to your comment or send them to me @Jeremy_NI if you have concerns over sharing them publicly.
Thanks for your help, sorry for the inconvenience, we're taking the matter very seriously and Brian's on it.
