Go to the top menu of this site under Company and look at the 3rd party devs. Rhthminmind, VNXT, CDSoundmaster, Room Hunters, all have awesome rever presets. Some even have scaled down demos. Get a few after trying demos. If you are like me, eventually you will get all of them, they all are great at different things, but very awesome.
most of the reverbprograms are sampled hardwaremachines like emtplate, L*****n, tc, eventide ... roomhunters theater is a real room, which has plenty of opportunities to shape the outcome. i like it a lot for real roomimpression. you can use it in every channel, when your computer is powerfull , and place the instruments in the depth and pan.
there are some other real rooms out there, but not that much at the moment.
system 1: windows 8 32 bit - samplitude prox/x3, tracktion6/7, reaper system 2: mac osx yosemite - reaper(32+64bit), tracktion6/7(32+64bit)
both systems on: macbook pro (late 2009), core 2 duo 3,06 ghz, 4 gb ram, graphic: nvidia geforce 9600M GT 512 MB
Well, a little update. I purchased the Theatre of Life and VNXT plate. The plate seems nice - sounds like a plate I guess . . .
The Theatre of Life is cool, but it's hard to control. Even a minimum mic depth, it can be too much reverb, and although it sounds cool on some instruments, it is pretty much unusable on vocals adding a weird nasally quality to everything.
Just my two cents. I'm thinking of going back to IR's for the most part because I love real spaces, echo chambers, etc., and unfortunately I don't think Nebula has enough dedicated libraries yet.
