How can I fade out a vst? (for old record effect to fade into/out)

[constantthought]

Probably obvious but after 2 or 3 years with Live 8 i still have no idea how to fade out a vst. I am trying to get this program which is basically an amp sim (for an old record/lp effect) to fade out after around 30 seconds but I am dumbfounded as how to approach this. The only option I have so far is to record/bounce down the entire song onto one track in this "old record" tone, then just fade the recording out while the original still plays but this doesn't come without its pitfalls.

I'd greatly appreciate some assistance guys and gals

I'll try and help.
So ...You have one VST instrument that you are applying an effect to, and you wish to fade this out, or reduce the amount of this effect gradually?
Anything like this I would look to use automation to fade out the track or the amount of effect in arrangment view
If this is what you need look at this tutorial I found:
