The Mercury Engine is the main synth engine for Spitfire libraries. It can be found in a lot of Spitfire libraries. Examples such as
Olafür Composer Toolkit,
Albion ONE,
Kepler Orchestra.
The engine has a lot of inbuilt FX. On the surface it looks like these FX can not be controlled in detail from the interface, however they can.
(Mac) CMD + CLICK (WIN) CTRL + CLICK, the FX at the bottom of the interface. This will open up more in-depth FX control for the chosen control.
A new area appears at the bottom of the interface which offers more detailed control over the selected FX.
