Are GA4 expansions compatible with GA5?

Thanks David. After doing this I see the Songwriters icon and all the other Agent files in my Library. I guess what threw me is window in the upper left hand of the GA5 program the drop down that says ‘Multi Program’, I click on it and it only shows the one icon, ‘All Agents’. I’m new to this but this strikes me as odd. Shouldn’t I see all available kits and beat files there?

My Songwriters kit and beats (and my other available kits in the Library) show up as I load a kit after clicking on the Instrument icon in the middle window and clicking the drop down menu. Is this the way it should be? Yep, I’m new to this and trying to sort things, I do love the sounds of the kits and they are very easy to incorporate into a song template.

Thanks for any help.
