Its a compressor called SunRuys. And will be part of a new plugin series that eventually merges into a big channel strip.
Here is a development screenshot, notice that the label still says SunSet.
The plugin is practically finished, just some finishing touches on the UI and some beta testing.
The compressor is supposed to lean on the clean/transparent side, though it works with slight amounts of saturation and noise. It is a hybrid between a feed back and a feed forward compressor.
Anyone wants to join the beta team pm me with your details (incl. email).
Cheers!
JM
