I’m wondering what I should do to get the Surge AudioUnit (Surge.component) to display in the Renoise plug-in loader. The VST2 displays a-ok, no worries there. Logic + ableton Live are able to stomach the Surge.component.
No nothing too dramatic! Apple changed the spec which basically means presets are not recalled when a song is saved and re-opened. It’s just safer to use VST (if you have the option), and there is no actual reason to favour AU really if you have a MAc.
