Thanks! I've installed PF v1 now. I think everything came together as expected, but here is what I see just in case I missed something:
In the PF v2 stand-alone program and the PF v2 plugin I can see the presets from Gearbox, PF v1 and PF v2. In the PF v1 plugin I can see the presets from Gearbox and PF v1. With just a POD X3 Live, I never had the PF v1 stand-alone. In Gearbox stand-alone I see the Gearbox, PF v1 and PF v2 presets, but of course the PF v2 presets are not compatible. In my DAW (Reaper), I can see the plugins for Gearbox, PF v1, PF v2 and all the PF Elements.
I thought I had the Gearbox plugin installed before, but it wouldn't activate. I dug around and found that I bought it for half price ($50) in Oct 2008 but returned it 2 weeks later because, IIRC, Pod Farm v1 had just come out for free. I got PF v2.5 for free in 2012 when they discontinued Guitarpost Online. It's the Platinum edition.
Am I correct that with all the PF plugins, I'm not missing any features from the Gearbox plugin?
