ok guys , looks like im in the mood , so illl post a Reverb tutorial for all those who are interested . After reading this article , i think , you should know most of the basic stuff 
Reverb is basically an FX unit , that simulates the acoustical reverberation of a space over time and frequency response ...
So, when dealing with reverbs , there are 3 main pillars that should be given special atttention , coz tweaking them defines what actually the reverb sounds like ...
1. Space to be simulated [ could be your bathroom to the Sydney Opera House ]
2. Reverb Time also known as RT 60 ... this means , how does the reverb time out over some time , until the signal has dropped below 60db , due to the continous diffusion of sound ..
3. Frequency Response - in ther words the color of the reverb . not all material sound the same in the same room and not all rooms sound same with the same material .... [ did tht make sense ]
anyways , so how to do this ....
as im using cubase now and then , ill post the technique on how to do it on SX / Nuendo ... but this applies to any host ....
reverb is always applied to a signal , be it mono or stereo , but the reverb unit should always be STEREO , unless you want to do something different with 2 MONO reverbs ...
as reverb simulates a space and since sound is perceived binaurally , Stereo Reverbs make more sense to me ....
proper reverb gives the signal some BODY , while imporper or a badly tuned reverb patch ONLY muddies the sound and mix making it less intelligible .....
so , here we go ....
Method 1 .... INSERT
use this method to apply a single reverb dedicated for a single sound [ like a lead patch or some sound FX sample ]
1. open the inserts strip for the channel you wish to apply the reverb to and select your favourite reverb plugin as a POST FADER INSERT .... now this is very important .... cubase mixer is designed in such a way that inserts 1-6 are PRE FADER INSERTS [ the amount of signal processed by the insert units on these slots 1-6 , is not determined by the fader position , they process the entire signal ] ...
inserts 7-8 are POST FADER INSERTS [ this means that the signal processed by th inserts on these slots 7-8 is dependent on the fader position .. so if the fader reads -20db and if it reads -5 db , more signal is processed when the fader is @ -5db ....
so , you dont want your reverb to be static , now matter how loud / soft your signal is [ which is what pre fader inserts do ] .. in the real world .. the amount of reverberation is directly audible by the amplitude of the signal itself [ thus we use reverb as a post fader insert ] as it dynamically adjust itself how loud / soft the dry signal is ....
2. after you loaded the reverb unit , some parameters need to be tweaked or you can simply browse thorough the presets that you like and use them ......
adjust the paramets for pre delay [ how much msec is the signal delayed before its is fed into the reverb unit ... bigger spaces have more pre delay and vice versa ]
reverb time .... how much time does it take for the signal to drop below 60db once the reverberation has begun ....
diffusion - this factor determies how fast the sound dies out , due to the reverberated sound streams bouncing off the surfaces and other material in the rooms , each absorbing some energy and slowly the signal dies out ...
room size - is as obvious as the name .... bigger settings make the reverb sound like a cave or a cathedral but lower settings simulate a bathroom , car or a garage ...
3, after you did this , advanced reverb untis like the waves RVERB and TRueverb , allow you to tune the Freq Response for the reverb , thus making it sound more natural ....
set the low shelving and high shelving filters accorindngly [ keep the wet / dry ratio high , so that you hear more of the reverb , then sweep the filter cutoffs to see , where they sound most natural ... and then cut or boost according to taste ]
4, last step , reduce the dry wet balance of the reverb unit to hear both the dry signal and the reverb signal as per your choice ....
MEthod 2 ... SEND EFFECT ...
1. create a new FX channel [ stereo and select a reverb plugin
2. once the channel is create , press ALT And click on the SOLO button of that channel [ thus enabling the Solo DEfeat function ]
3.open the channel editor for the signal that you need to revern and on the right side of the EQ are the 1-8 sends listed ..... now noticed , unlike inserts , all the sends of cubase , can either be PRE/POST FADER sends , depending on how they are configured ...
to change between PRE /POST fader sends , toggle the button next to the power swtich over each send ...
now select send 1 , switch it on , click on the black line and a menu apperars , selct the reverb FX channnel you created from this menu and then drag the blue line unti it is 80 % of its entire lenght .. this way you allow more of the signal to be sent to the reverb unit and thus , help you to tweak the the reverb settings easily ....
4. once again , open the reverb plugin , tweak all the parameters as i explained abouve and when you think its fine ...
come back to the channel editor and slowly start decreasing the blue line , until you just hear both the dry and reverb signal in perfect ratio .....
Reverb FX channels , can be used to send the same reverb to process multiple tracks @ the same time , thus saving CPU .... for example is a reverb tuned only for the SUb drum mix ...
now im really tired of typing and i think i covered more or less , all of it ... if i missed out something or u need clarification on , please feel free to post 
thank you ,
respect .. chandan !

wow, tnx 
i only have one problem... I've always been told that inserts are for dynamics processors, and not for FX... Is that wrong? |

no, thats right, but there are no 100% rules! so do what sounds best 4 u.
another thing i got good results of is some sort of asistent reverb.
for example let's reverb our percussion set.
lets say we have a lot of different samples , and we want some with a large fx reverb, and others quite dry. here u have the problem, that if u use too much differnt reverbs, the whole percussion section doesn't sound like one piece.
thats why i use insert reverbs on the sample tracks, which are supposed to have these large fx-rooms.
than i make one effect-channel delay, not to big, just a decent one, and route all percussion tracks (incl. the ones with the insert reverbs) through it.
now the whole percussions are in the same "room".
