Using AL4 in Reason 10. I had the problem with the program change and fixed by deleted the default concert patch. But now if I load a preset in an instance of AL then edit the patch in the V collection synth. If I don't save the edited patch as a new preset then if I reopen the project or even if the computer sleeps then wakes up then it loses the edited patch. The place in the AL screen that normally has a pic of the synth is black but the patch name is still displayed with an asterisk next to it (as I would expect). I can only get sound back by reloading the saved preset therefore losing my project specific edits.
