Back to the original question… Yeah, it’d be a good idea to have an offiical place for tracking progress. Short of that, I can summarize our internal list here as of now:
Impromptu, Venom, BaconMusic: Some initial tests re-compiling the original code as MM plugins. Mostly successful but still just in the initial phases.
Sapphire: We ported several modules fully (Galaxy, Frolic, Glee, and Hiss). Most of the others work in some way but need some changes to make them more suited for MM. Elastika in particular “works” but is very CPU heavy and needs optimizations.
Prism: Plan to help port.
Surge XT: on the wish-list (no developement done yet)
Several other developers are working on plugins, too, including Vult and Unfiltered Audio.
