Thanks - I have the same question as I too have Sonic 3 already installed and don’t want to duplicate the sample library/presets on my HDD. However, by removing Sonic 3, I’m assuming that projects referencing any of those presets would need to be re-assigned to Halion 6 presets - assuming they are available and not customized/tweaked in Sonic 3 to begin with. Maybe that’s an understood risk but something to point out prior to removing the program and content.
