I will have help with tempo Swing feeling in Strummed Guitar 2. I am intresses about Strummed Guitar Strummed Exklusiv. But can i by upgrade to Strummed Guitar 2.
As far as I know there's no upgrade to Strummed Acoustic 2. I'm not sure what you're looking for regarding the swing, maybe you can check the manuals for both libraries to find out? Here they are:
