just had some WTF moments why did my changes not save? I have some parameters on Soundtoys and Valhalla VST's which have macro assignments. I made some changes directly on the VST's and they did not save. I tried again on the Valhalla delay and it then did save. But then i checked my Filterfreak and again I made the change I wanted on the VST itself, saved it and it did not keep!
I hope this is a bug, I've certainly never noticed this before.
