OK, I want to learn more about reverb plugins, becuase all these knobs and sliders can get confusing. I understand what most of the knobs mean, but I'm confused about the "size" knob. I assume this controls the virtual room size? If you make the size really big, does that mean your signal needs to be big enough to fill that size?
Like if you take a string quartet and put it in my bedroom--the room's too small and the sound is too loud and, well, bad. If you put that string quartet in a small to moderate sized church, I'm sure it would sound very nice. However, if you put that string quartet in the Atlantic City convention hall the sound would be very thin and echoey. That's why the Atlantic City Convention Hall has the world's largest pipe organ in it--it's the only instrument that can fill such a large room with sound.
So with reverb plugins, should the "size" of your virtual room be appropriate for the size/power of your enseamble? And what exactly does the "size" knob do to the signal?
