Download link: SPC Plugins NKS presets
Plugins included:
ArcSyn
Updated these with factory NKS and previews for the new beta which supports Apple Silicon - unfortunately not compatible with the previous version so I had to redo them all. If you are still on Intel or the previous version use the old NKS
Note this is one of those plugins where changing the NKS does not update the preset name in the plugin but this is purely cosmetic - the patch changes correctly.
