For some reason, every time I open a session (after it has been saved and closed) all instances of the MiniV are on their default patch. I always try to save my own patches (if I know I definitely want to use them) however sometimes tweaks are made, or I've just been jamming with a particular sound. It means if i save this and open it later, all that info is gone. It's just annoying really.
I'm using Logic Pro X and have the V Collection 2.0 (however I have updated it in order for them to work in Logic X / 64 bit). However they did it did this before. None of the other synths do this, just the MiniV.
