Re: the other post, when I tried to post to it the forum advised, due to it's age, to start new thread. Also, as stated, there were no replies to it so I didn't think a link to an empty discussion woud be of much use.
Also, as per the OP, the specific plugins are the V-6 collection. Seems consistent mis-behaviour with all the ones I've tried. I'm on a Mac and the same behaviour seems to occur using VSTs or AUs but I tend to use the AUs.
I don't use Windows and I'm not sure the host I'm using (Gig Performer or Ableton) is the issue. Would it not be the plugin that has some sort of saveable default?
