I'm new to LPX. I installed only the essential contents because I am a minimalist and because I don't need additional 70GB of Logic instruments. However, it appears that additional downloadable contents offer additional effects. Case in point: there's an additional item entitled "Reverbs," larger than 2GB in size. Is this a collection of additional reverb algorithms? So, can anyone tell me whether additional contents come with more effects? If so, I might install them (I have a big SSD anyway).
