This has been driving me crazy. I know how to save presets but sometimes I just want to open a patch and tweak it and then close it and have live remember where everything was set before. As it is if I tweak a patch and close it every single parameter resorts to it's default state. On top of that it also erases any presets I made before editing the patch.
I'll be super happy when I figure out how to squash that problem.
edit: more info, if I save the live set I can open the patch and edit it and when I close the editor I get my settings back BUT the problem there is that during editing the settings are all at default. Would be excellent if the settings made in live were retained when I click edit.
