I mainly use Studio One for mixing live worship teams on Sundays. I have 13 scenes set up for each Major and Minor keys. The problem is if I make one small change on any plugins, then I'd have to resave that change in all the 13 scenes. Having a safe scene recall at the plugin level would be such a time saver meaning only plugins that don't have the safe button activated will be recalled by that scene.
Currently only ProTools and Cubase have that feature. Not the safe button but similar.
