When I create/edit Virus TI patches I'm usually not using my DAW. I've never understood why Acess doesn't provide a standalone editor, but now I've found an elegant solution: savihost is a small application that can turn any plugin into an executable. No need to install it: all you have to do is copy the application (savihost.exe) in the same folder as the vst and rename it with the same exact name as the vst. Then you can create a shortcut and launch it from the desktop or from anywhere else you wish. Savihost is free but you can paypal a few bucks to its creator if you find it useful.
